You mean you used 'cdrecord'??
Well, it depends on how you burned it. I'm not really sure on all the ways you can mess up your usage of cdrecord, but one of the little jokes I have found on my box is in the man page of cdrecord under the bugs section:
Code:
BUGS:
Cdrecord has even more options than ls.
So without knowing _how_ you burned the file it's a bit difficult to establish where you went wrong. But my bet is that you didn't use 'mkisofs' first so that your .avi would be burned in a format that Redmond can recognize.
Just build a .iso from your file(s) and burn that as an image. In it's most basic format, using all the defaults, just:
Code:
mkisofs -o name.iso movie.avi
Should get you a long way.
