[Amalfi Marini II]

hi guys ! I got the same problem when doing a DVD->DIVX convertion of a small video, I used Nandub and the sound was mp3 48k mono 22050 Khz. The resulted video was a 60 fps movie that run like hell while the sound played normally. So I tried again with another program, Virtual Dub Mod. it worked perfectly.
If you already downloaded those videos just try to slow it down to 30 or 29,976 fps (or what ever) aplying "frame rate adjustment" option in Virtual dub mod's framerate panel.
Good luck, I hope this helps
