    Angry .ty -> Mpeg errors

    I don't ever seem to be able to convert .ty to .mpeg. I always get a "gop" error. I've tried several different shows like 24 and so forth; the idea being that I can watch some things on a PC/Laptop. The Tystudio documentation mentions "Generic MPEG2" and "no Transcoding" which I do. The video is viewable just fine in Tystudio. I did successfully make 1 VCD. But MPEG through MS Media Player never works. Here's my most recent attempt, and yes, I do move the cuts around some as well:

    MS media player (unless I'm mistaken) does *not* ship with an acceptable MPEG-2 decoder for use with TiVo generated streams. That could be the problem. Try using a DVD playing program (PowerDVD, WinDVD) and choose 'Open Media Files' or something like that to get to the .mpg file you saved.
