Winimage will extract .img files that you can then burn with whatever you want. The only problem that I ran into was that the DVD won't play on my regular DVD player, but works fine on the PC.
Normally what I do is open a video cd image with Isobuster and just extract the video track as an mpeg which I then upload to my modified xbox to watch on the tv
If you then re-encode them to video cds it usually allows them to play in the dvd player as well with mine anyway
