Feature request X 2

1) MKV playback---including showsqueezing to MKV with the choice of keeping existing audio (5.1) or transcoding it.

2) ISO playback--I was cleaning up my hard drive and found some PPV fights that I made into ISOs with BTV, VRD, and GUIforDVDauthor. After all that work I still need to keep the original mpeg for playback in BTV and the ISO if I want to burn it again.

Thanks for consideration.
