[CentOS] Cannot play rmvb video files after burning to DVD

Hi,

I am running CentOS 5.2. I tried to burn rmvb video files to DVD+R
disk using Nautilus 2.16.2, the files were burned to the disk, but
could not play it back with errors "Unkown file format". It was no
problem to play the same file located on the disk. Any advice please?

Thank you.

Kind Regards,

JH
