Hey guys, had a problem I can't figure out. I've downloaded some MPEG-2 SVCD files before that were in PAL format. When I burned them to a DVD-R, my DVD player would say "wrong format". To fix this, I de-multiplexed the files in TMPGEnc and converted the video to SuperVCD(NTSC). I then multiplexed the new NTSC file with the old audio. It worked well for me. However, the video I'm working with now won't convert. When I drag it into the Video source of TMPGEnc it says, "Can not open or unsupported". What am I doing wrong?
