Play RMVB movies on iPad2

[BA21]

Is there a way to move RMVB movies on my computer to iPad2 and play them, or do I have to convert them to iPad2 compatible files, such as MP4 before I can move them to iPad?

You can go to App Store and find some apps that can play rmvb files. I use OPlayer myself, but there are others available. You can move the files during sync in Itunes.
