Advertisements I used tivodecode to turn some TiVo files into MPG files on my Mac. No errors were reported. However, a few of the files won't play: previewing them in the Finder (by pressing SPACE) brings up a non-video window and it does nothing. Actually opening them in Quicktime Player brings up an audio-only window, and it doesn't do anything either (doesn't Play at all). But VLC will open and play them just fine! Well, the first 1 or 2 seconds (of lead-in commercials) are pixelated. I am guessing the files may have been very slightly corrupted when they were still in TiVo format, although I *think* they originally played on the TiVo device. I haven't looked at these disk files in years until I did a mass conversion today, There was no evidence of anything wrong, except that when converted to MPG, they didn't work. Quicktime still knows how long they are supposed to be, but doesn't seem to recognize that there is a video track there. But VLC doesn't have any problem. Just passing this along in case anyone else has this problem. Note that you can make VLC your default video player on the Mac. This was on: OS X 10.9.5, Quicktime Player 10.3, and VLC 2.2.1, and I also tried it on an up-to-date El Capitan. So don't despair if you have discovered some flakey MPG files. Just use VLC to play them!
