I have used videora and magic video converter (along with a couple others) to convert videos to be in ipod format. However, when it comes to certain avi files, after it converts, the audio and video are way out of sync. This is weird cuz when i convert other avi files, it converts just fine. I read somewhere that you can maybe fix this with testing different bitrates, but that seems like it would be so much trial and error. Is there a faster or better way?
