I have a Nokia 6102i and I need to edit some of my 3GPs. In order for me to do that, I need to convert to mpg/mov/avi/wvm first unless theres a 3GP video editor out there(?). If I convert to mp4 in Nokia's multimedia converter, the playback video/audio is out of synch (sometimes the video will play 2X fast, stop, fast, then normal speed, while the audio is ok). Besides this, I've also tried Xilisoft 3GP Converter and Total Video Converter, and tried to convert to all different video formats, I have the same problem if not worse.
I have used many times this converter: http://www.imtoo.com/3gp-video-converter.html and videos have always worked like those should be.
its ok, thanks tho. i think its my phone, the 6102i is a piece of crap anyway. even the connector cable for it isnt very friendly, i have to unplug and replug the connection everytime i want to transfer files..
