I recorded some home video with a Sony Digital 8 camera, then recorded the video onto an Archos AV400 Pocket Video recoder. The clip was saved onto a WinXP computer where we watched it in WMP. I transfered it to my PowerBook where it plays just fine on Quick TIme (not pro). However when I play it with VLC on my PBook, the video is fine but no sound. I have other clips that I watch with VLC that sound fine so I'm not sure what the problem is. Any suggestions?
