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
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.
