Now I do not know much about this converter, but it has been successful, and I have been able to watch videos on my iPod video. The problem now is that I can't watch most of the videos I watch now on my computer. It would give the error box saying the video player encountered a problem and has to be ended. This happens with Media Player Classic, WinAmp, RealPlayer, and Windows Media Player. The only player that doesn't give this problem is VLC Player, but VLC doesn't run well on my computer.
I tried to reinstall Xvid and Divx codecs, but still no luck. I don't know if it's a codec problem, or if the 3GP_Converter messed with my computer's video codecs.
