I have been trying to figure out why tmpgenc does this but i haven't figured it out. I recorded an hour long tv show from my WinTV PVR-150, it opens fine with windows media player or any other media player. The problem is when i open it with TMPGenc XPress to cut out commercials is says the video is only 12 minutes long and i know its not. So if i go cut the commercials out it will only let me go that far (12 minutes). I have already went to the options and moved the directshow priority up in the list and that didnt fix it. Just wondering if anyone else had run into this problem, and was able to fix it. Thanks in advance!
