    Toast Dvd Video Not Playing Back Properly

    In case anyone stumbles upon this in the future I have finally got to the bottom of it. I'm in the UK, London region, where we went over from a mixed analogue/digital signal to digital only. When that happened we got lots more channels, but they also seem to have changed the broadcast parameters of the stream. In particular, many channels took to broadcasting with a GOP number well over the DVD spec of 15. The GOP - or Group of Pictures - is basically the frequency with which a key frame is broadcast. My video editor (ViideoRedo for PC) defaults to outputting whatever GOP number the input file has, and it was this that Lion QT and Toast didn't like when the GOP number increased. I now output with a GOP length of 15 from VideoRedo and the problem is fixed. it takes an extra minute to do this, as a minor recode is required, but then the disks or mpegs play just fine. You can edit the cfg files for the preset output styles so that the default is a recode to GOP 15, to save you resetting it every time. Hope this helps someone.

    Choppy Video On Dvd Playback

    Hi Has anyone solved the long-standing choppy video problem on Lion? I had everything working fine under SL, but since Lion I have had nothing but trouble with video, and DVDs/mpeg2 especially. QuicktimeX hates mpeg2, freezes on scrubbing and gives choppy playback, as though it is getting audio and video out of sync and having to resync. Quicktime 7 Pro, on the other hand, plays mpeg2 just fine. (QTX is ok with mp4/h264). I had Apple Support on to this and we ascertained that QTX under Lion is much more fussy about its mpeg2s than QTX under SL. In particular it was picky about what application had created the mpeg2s and its compliance to the standard. My worst offenders are created by exporting out of EyeTV. Other mpegs edited using VideoRedo for PC in my W7 VM are better. I'm guessing that EyeTV is making low-compliance videos. And, it seems, anything that uses QT to do its video playback has the same problem - I presume that''s how DVD player works and it is having trouble with mpeg2 videos out of EyeTV burned as dvd-video discs using Toast 10. Presumably it is using QTX for decoding and display and hence the same problem. My assumption is that Toast is not the problem - it is the playback component which is. So my guess is that QTX mpeg2 codec is primary cuprit, I just can't fix it.any thoughts gratefully received. TP

    Toast Dvd Video Not Playing Back Properly

    Well now, this very interesting...... I made a .toast file, mounted it and played it in DVD Player - crashes in the same place. So I guess that proves it isn't the writer.

    Toast Dvd Video Not Playing Back Properly

    Thanks for your very helpful ideas. I already have Toast set to never reencode, so they only multiplex now. And I already use Verbatim DVD-Rs, so my mind obviously works the same way as yours! I'll try the disk image route and see what happens. Then I'll try the re-install. Back in a few hours, when I have done all that. Thanks again.

    Toast Dvd Video Not Playing Back Properly

    Update I tried slowing down the burn - no good, same crash in same place. Error message from Apple DVD player attached. Error-msg.rtf
  7. Hi I've been using Toast in various versions for years, but am now having real difficulty getting DVD-video discs burned using Toast to play in any player in full. I'm taking TV show mpegs recorded with EyeTV, exporting them as mpegs then burning them. Typically they will be 3 60 minute TV shows or a couple of TV movies on one disk. The menus play fine, the disk starts ok and often track one is fine throughout, but tracks two and beyond deteriorate at the end of each show and often crash out beyond the 40 minute mark. Other times they suddenly behave as though they are on super-fast scan mode, showing a freeze frame, then another several minutes on and so on. This applies if playing back in Apple DVD Player, VLC, Windows Media player for a separate pc or a dvd player attached to the TV. I initially thought my superdrive was getting worn out and was burning faulty disks, so I had it replaced - the Applecare support guys said there was a drive fault so it was done under warranty - but it is still doing it. I'm on Snow Leopard and Toast 10.08. It is a 2009 MacBook Pro 17" machine with its DL superdrive. The issue seems to be that Toast is burning slightly non-compliant disks. At the moment I can't trust any disk I burn in Toast and my wife is getting very p---ed off with missing the end of shows I recorded! Can anyone help, please?

    MPEGs sometimes burn with scene menus, sometimes not

    Hi Thanks for the reply. There is an option to change the frequency of auto chapter markers. Are you saying this doesn't do anything if the source is mpeg2 and Toast will always use 5 mins? My point is that with some mpegs without time code breaks this auto process doesn't work, they remain stubbornly chapter-markerless, whether it is 2 mins, 5mins or 10mins. There must be something different about these files - and hence presumably fixable - but I can't see what it is. Thanks anyway. TP
  9. Hi I'm having a mystifying problem with making dvds from mpegs, mostly made by exporting mpeg program streams out of EyeTV, but some from a Windows box as well. I have Toast set up by default to give me a chapter point every five minutes and the Include Scene Menus box ticked. 90% of mpegs cooperate, giving me nice scene menus. However, some just won't, whatever I do. Last night and the night before I recorded a two part mini-series and exported out mpegs from both, trimmed to lose the pre and post programme fluff. One gives a scene menu, one doesn't. Same size file, same resolution, same TV channel, same recording equipment, different result. Wierd. I've tried using Mpeg Streamclip to make a new mpeg from the uncooperative one, no difference. I found the option to put manual chapter points in in the clip edit menus, so I inserted a load of chapter breaks. No difference, still no scene menu (or chapter points, as the burned dvd has only one chapter). I've found from experience that I can put in a manual break into an EyeTV recording and then use the Toast option to send the recording to Toast, and when I do this I get the chapter points I inserted, but if I don't insert manual breaks I get no chapters, regardless of what I have set in Toast (i.e. it won't do auto-chapters with EyeTV files the way it usually will with mpegs). I can understand this, as the EyeTV file is presumably an mpeg in some special container. The trouble is it produces files which as 15% bigger than the mpeg which you export from it, so if I use EyeTV files directly I get less per disk (and in this case one EyeTV file plus the working mpeg doesn't fit). It's not the end of the world, but it is very irritating. Can anyone shed any light on why this is happening, please? Thanks in advance for any suggestions. TP

    Toast Burns From Eyetv With Wrong Or No Sound

    Thanks Ricky I'll give these a try. You wouldn't have thought that the ability to choose an audio track to burn would be beyond them, would you! Thanks for your help. Regards Tim
  11. Hi I have been having trouble with burning dvds from recordings made with EyeTV 1.8.4 (and then v2.0) which came with my Terratec DTT product . Basically most recordings burn fine to dvd with Toast, but maybe 10% burn with the wrong or no sound. This problem seems to be related to the second audio channel sometimes used by broadcasters to record descriptive commentary for the visually impaired. The 'no sound' problem seems to occur when Toast takes that channel even though it is empty. Two examples. This weekend I recorded the movie Shaft from UK Channel 4. On burning I get only the second channel with additional commentary (a lady describing what is happening), but no actual film sound at all. EyeTV itself plays whichever channel you select in the audio menu. However, whatever export options I choose I always get the second channel only. I have tried the direct Burn with Toast route and the Export for Toast route - same result. Last night I recorded a documentary on BBC4 - this has no sound on DVD because the second channel is empty. What we really need is a selectable option to choose which audio channel to use, to prevent Toast getting confused about which audio to use. I see on this forum that this is a known issue but the advice there - select the channel you want before export and/or Export rather than direct burn - is not helping. Has anyone else resolved this problem? Regards Tim Pollard

    Automatic Chapters In Dvd

    Hi I've discovered there is a workaround for this. Simply use the EyeTV edit functionality and insert edit points where you want the chapters to be, as though you were going to edit out a portion. Don't move either handle (otherwise you would be editing stuff out). Do this wherever you want a chapter point to appear then close the EyeTV file. When you burn to toast (or export out) the file retains these markers and Toast automatically puts in the chapter points. The benefit to this is that you can put in the chapter points at scene changes rather than randomly. Regards Tim
