SMS Playing xvid from a cdr ??

I am running smsplayer 2.5 by using the memory card exploit. I successfully burnt a cdr disk using cdexplorer, and cdrdao, but I keep getting the "Illegal Disk" ERROR. Do I need to have the files, cdvd.irx and, or audsrv.irx on the memory card to make it work? If so, where do I put them?

Thanks!
