I have a source video that is in the IDIOTIC framerate of 24fps, so i want to use the TMPGEnc OUTPUT TO AVI FILE feature, and change the framerate to 23.97 FPS so that it is standard compliant framerate, but when i output the AVI file and it is finished, windows media player says, CANNOT PLAY BACK FILE, FORMAT IS NOT SUPPORTED, DivFix says THIS IS NOT AN AVI FILE, and virtualdub says CANNOT DETIRMINE FILE TYPE. WHY!!??? i used the OUTPUT TO AVI FILE FEATURE, and the output file is NOT AVI!!! I NEED TO KNOW A SOLUTION!! this problem is really pissing me off, TMPGEnc is a real pain in the ass.
