I have not been able to play avi files that I copied from my canon digital camera on my epic. Finally found a free video player called arcMedia which plays avi files, but the video quality is completely messed up. I read about Handbrake software using which we can convert avi files into mp4 files. But I have a huge collection of avi files and d not want to be converting every single avi file so I can play it on my epic. I also tried finding Rockplayer in android marketplace, but could not find it from my epic phone. Any advice and help on this topic would be greatly appreciated.
