I realize there are many threads about copying video files to/from TiVo and discussion about what programs to use etc. Codecs and encoding can be complicated, I have dabbled in amateur video editing and DVD burning beyond the very basic programs and frankly did not enjoy it. Any way, using some commercial capture hardware/software a few years ago I have mpg files that are in DVD compatible format. Using TiVo Desktop, they show up on my TiVo Premiere, but show a length of zero minutes and do not play. Does that indicate an incompatible encoding or some other problem? An unrelated oddity (I think) is that the videos on my PC that I set up for sharing with my TiVo then show up in the TiVo recording list of TiVo Desktop like shows I transferred from the TiVo, which makes no sense to me. Is this normal behavior? I was just seeing if I could use the TiVo to view my home movies easier than hooking up the PC, but does not look like it.
