Hi, searched the threads and found that to convert all avi files to mp4, you would need to use handbrake. What baffles me is that some of the video files that I have is a .rmvb file which opens with real media player and vlc. However, I am unable to convert on handbrake. Handbrake shows "Source not found" whenever I try to convert. Can anyone advise how to convert or is there a work around solution? Thanks in advance.
