If it plays there, you could TRANSCODE it to something Nero's video CD creation could use. This is not an offer of any tutorial but to share it's what I used.
I have a video of RM formt. I am using Nero for writing CDs into VCD from RM. It is getting some error mentioning the selected format is not compatable. Please help me to convert the RM video to VCD. Is there any other free software for converting RM to VCD?
