I'm converting certain MPEG and AVI-files to the 3GPP-format, for use on Nokia phones 3650 and 7650. I use the multimedia convertor from Nokia. With certain movies, the audio is nog synchronized with the video, but only when I play the 3GPP-movie in the videorecorder of the phones. When I play the movies on my desktop pc with the Nokia MultiMedia Player, everything goes perfect. Does anyone else have this problem?
