RMVB recorder?

Hmm..i got a few rmvb file on a cdrom. Each is about 30mb. When i try and copy them to my harddisk, all except 1 worked. I got a CRC error.

funny thing is i can play back the file, but not copy it to my harddrive. Is there a way while playing the rmvb file, to record it and save it as an rmvb again? Hope you guys can provide me with some links.
