some AVI files generate a "source frame rate is too low" and say that the AVI frame rate is only 2 fps, while Windows shows the correct 25 fps value... re-processing the AVIs on VirtualDubMod fixes it but takes time... anyone knows how to fix this problem?
Caution: changing (I don't know it it was what you was meaning of 'processing') the movie's framerae with VirtualDub causes A/V de-synchronization. Otherwise, if it is just sort-of header error and VirtualDub shows the correct framerate, try to frameserve (File___Start Frameserver; double click auxsetup.exe if the frameserving client is not installed) the AVI with VirtualDub. Otherwise, maybe the use of some video-fixer?
