I may have stumbled onto some insight into timecode skips and stream
oddities, but I'm not educated enough to know. I have been using
ExtractStream 0.3 and the 0.3 version that came with TiVo app off and
on. I was losing several seconds of shows at the ty stream breaks so
I started mucking with sendstream. On one half-hour Futurama show, I
recently used ES for the first and third segments, and had to use SS
on the 2nd because ES was skipping large amounts of bad blocks (at
least a couple seconds of a funny part). I then used TyConvert.exe
on the 2nd segment to split it into 2 files like the ones I got from
ES. After using TyConvert with the "Don't skip bad blocks" option
turned on, I muxed the audio and video with TMPGEnc and noticed that
roughly the first second of video was from a previous Futurama
episode. The audio was correct, but the first half second of video
was clearly from another episode (that's on my TiVo somewhere), and
the 2nd half second was sort of a blurry blend between the wrong show
back into the correct show. So is Sendstream (0.2) messing up? Do
the files on the TiVo actually contain these artifacts from other
shows? Do the mfs tools or drive expansion methods cause some minor
glitches like this? Were it not for that one second glitch, I would
have a flawless backup of the show. If I went back to 1 virgin
drive, would I have this problem?
I am willing to do anything you might need of me to help look into
this.
