Best solution for DVD ISO´s?

[jazzl]

I just watched the youtube clip that was posted here earlier and I realized that if I launch from the IFO file in VIDEO_TS, it´ll all be fine with menus and everything!
However, I also found out that what I was looking at is NOT an ISO, but simply a copy of the directory structure on a DVD.
So I went to find what indeed is an ISO, but to my great disappointment xbian did not do anything at all. Could it be that there are certain types of ISO´s that Xbian won´t read? I´ll try more when I come home.

Thanks!
