    Toast Disk Images Too Big To Burn

    It sounds to me as if you do not have "Use Fit-To-DVD video Compression" selected (bottom left of the Copy page). Going via a disc image I routinely burn 2 full length feature films onto a DVD. George

    Upgraded Toast 8.0.3 To 8.0.4-dock Problems Again...

    I have ditched Toast 8.0.4. Since updating from 8.0.3 I have had some strange behavior. First a disc writing failure that might have been a faulty DVD-R, then a multiplex process in which the progress bar stuck at 21% even though the items being multiplexed continued to be listed and, final straw, Toast terminated unexpectedly part way through writing a disc. 8.0.3 has never given me any problems so I've gone back to that.

    Continuously Running Optical Drive

    I have recently replaced my G4 with a Mac Pro. While the fan noise from the G4 was considerable the new machine is very quiet indeed. The loudest noise it makes is the white noise from the optical drive when it is running. I was disappointed to discover, therefore, that when playing DVDs created with Toast from eyeTV recordings, the drive runs continuously whether using the Apple DVD Player or VLC. If the film is paused, the drive stops but it starts up again as soon as playback is resumed. This does not happen with commercial DVDs. Anyone with ideas on this problem?

    FilmFour to eyeTV to Toast 7.1.2 to DVD

    I have now used Toast 7.1.2 a number of times with eyeTV recordings. The famous error -50 during multiplex has not occured. That seems to be cured. I have tried to process one recording originating from FilmFour. Toast recognised the encoding problem and automatically re-encoded for compatibility with DVD. It is a long job: about half a day on my machine. The result is not quite satisfactory. The resulting disc image plays on the Mac DVD Player and does not stop or crash the player as these films did before without re-encoding. However, the playback contains frequent little jumps as if a few frames are missing. This is too irritating to watch. I have seen the same effect before when I tried exporting a FilmFour reecording from eyeTV for QuickTime. It was just as lengthy a process. When I tried to run the disc image with the QuickTime Player I found video and audio were badly out of sync (by about a second). I then tried playing it with VLC. Sound and vision were now perfectly in sync but there were little jumps in the playback exacty as described above. Because the time involved I have tried only one film to get each of the results reported.

    Toast RAM Usage

    It turns out that this is entirely normal behaviour of a Unix application. The reuse of inactive RAM naturally does not show up on the Activity monitor pie chart as the status of the RAM does not change. A low pool of free space and the distorted playback of sound samples is not cause and effect but is just a coincidence. Apologies for introducing a non Toast problem but the connction did look convincing.

    Toast RAM Usage

    I have 1.5GB of installed RAM and, using the Activity Monitor, I have observed the effect of Toast on its allocation. Before starting to burn a disc, the free RAM stands at about 600MB. As soon as burning (in Data mod) begins, inactive RAM starts to increase at the expense of free RAM in a series of steps. This continues until the free RAM has fallen to a tiny 18MB and stays there until burning is complete. On releasing the disc from Toast the free RAM rises to 40MB and when Toast quits it rises again to 60MB. Does this matter? Well, yes it does. If I now run a music application, which requires lots of RAM to accommodate large instrumental sound samples, it is unble to cope with playback. Presumably, in the absence of free RAM, the samples are being streamed from the disc. The only solution is to Restart the machine. This brings back the 600MB of free RAM and the music program can playback as usual. Why is Toast having this irreversible effect on the memory available to subsequent applications?

    Effect of Data option on Copy

    The situation has got worse. I don't seem to be able to write DVDs at all now whether Video or Data, with Toast or the Mac burn facilities. It looks very much as if the drive as failed. I've arranged to have it relaced. Thanks for your interest though.

    Effect of Data option on Copy

    Thanks for this. It broadly represents what I would have thought before the problem arose. There just didn't seem to be any other explanation for a disc image working from the desktop but not from a DVD-R. Since Disk Utility did create a valid DVD from the same image, the problem has to be with the Toast Copy operation unless it was a bad DVD-R. As I have rarely encountered one such, I am reluctant to think I found two in succession. Any alternative suggestions will be gratefully received.

    Effect of Data option on Copy

    I think you have misunderstood me. I had previously been burning Data discs and had set the option "Mac only". Toast remembers all settings when you rerun it so, when I later came to copy the disc image, this option was still selected. It was precisely because there is no call to look at the Data window at this point that it didn't occur to me to change it back to the default. In any case, I never imagined that it would matter. But the evidence is that it does. These options have no counterpart in Disk Utility which I suspect burns discs to be compatible with all types of DVD player by default. That would certainly be the Mac way.

    Effect of Data option on Copy

    I think that the settings on the Data page of Toast (Mac only, Mac or PC etc) influence the copying of video disc images. If so, this doesn't seem to be mentioned in the manual. Until recently I have always accepted the default of "Mac or PC". But the last time I burned a Data DVD I chose "Mac only" as it seemed to offer advantages. All was well with the resulting discs. When making video discs (from eyeTV recordings) I invariably create a disc image, which I can test on DVD Player, before using Copy to burn the DVD-R. It didn't occur to me that the Data page setting might be relevant to this process but the next time I copied a disc image, with "Mac only" still selected on the Data page, the resulting disc would not mount on the Mac. I repeated the copy with the same result. Finally I performed the copy with Disk Utility and all was well. The Data option was the only thing that was different from all previous DVDs and that strongly suggests that this was the cause of the problem. Was I perhaps, unwittingly, trying to make a Mac only formatted DVD which, as far as I know, does not exist?

    Mac OS error code -50 burning from EyeTV

    Thanks for this suggestion but deselecting this option has no effect. Last night's broadcast of "Short Cuts" had an information content of 17 MB per min and, sure enough, it plays without the facility of fast forward. The menu button is also disabled on the Mac DVD Player. It is significant that none of the low content transmissions have come from the BBC. It seems to be that the commercial channels are applying compression to some films but not others. I would like to know if other users can confirm or contradict my results. eyeTV seems to cope with compressed films successfully but Toast doesn't. Is this a shortcoming that can be correctd or is it a more fundamental problem?

    Mac OS error code -50 burning from EyeTV

    Having now had time to build some experience with eyeTV and Toast 7, I am able to draw some pragmatic conclusions. My eyeTV program is up to date and I am using Toast 7.0.2 as 7.1 (pre update) continually led to error -50 when multiplexing. Trying to transfer a feature film to a video DVD has produced, for me, 3 possible outcomes: 1. Complete Success. (24) 2. Film can be watched but will not fast forward and crashes DVD Player if I attempt to step through the chapters. (3) 3. DVD Player crashes early on playback, usually during the credits. (9) I noticed that the films in category 1 all had file sizes of at least 2GB and frequently much more. This suggested that the problems arises from excessive compression of the transmission. Obviously the file size is also related to playing time so I adopted an index calculated by dividing the file size in MBytes by the playing time in mins. If this figure is at least 24 I can be very confident of success. Most of the complete failures are in the range 18 to 20. The 3 films in the second category, surprisingly, have indexes of 16,17,17. I have no explanation for that. I find that all films made specifically for TV, such as Poirot, West Wing , Maigret and Desperate Housewives, give no problems and that they typically have indexes of 24/25. Perhaps someone or knows about compresssed TV transmission could comment.

    Mac OS error code -50 burning from EyeTV

    I tried the tip, suggested in another thread, to use Export For Toast to transfer recordings from eyeTV to Toast. Sure enough, this has cured the problem of the missing soundtracks. I have just downloaded an update to eyeTV (2.3.1) and will test it out during the day.

    Mac OS error code -50 burning from EyeTV

    I have followed this discussion with great interest and, having replaced Toast 7.1 with 7.0.2, have not encountered the Mac OS Error -50 again. However, I am now finding that many films finish up in the disc image with no sound track. Has anyone else got this problem? It did happen once with 7.1. I am not interested in playing DVDs other than with the Mac DVD Player.

    Can't Burn Video DVDs from EyeTV

    I recently had to clone my startup disc to an external drive, replace the startup disc and, finally, clone back to the new disc. Since then, all attempts to burn video DVDs from eyeTV recordings have failed during the multiplex phase with Mac OS error -50. Also, the Toast button on the eyeTV recordings page does not work, "Recording cannot be exported". I have reinstalled both programs to no avail. The Elgato service facility is stumped by the problem and has suggested a "scattergun" approach of trying everything that has ever solved a Mac OS problem. Can anyone suggest a more direct solution?
