✔ 最佳答案
If u really want to watch RMVB files, first u should have software like Realplayer. For me, i never use Realplayer to watch RMVB files, because Realplayer is not user friendly. I usually use a free software like " Media Player Classic" to watch RMVB. This software is very simple and FREE. it can play almost any kind of video files, like avi, mpeg, rm, rmvb, dat, wmv, etc. I highly recommend it.
