Hey.
I got the same problem. Check this great page about converting formats:

This tool will convert your MDF files to ISO:

If you have the patience, check its source. Looks pretty amateur (of course, it is still at its 0.2 version), but it gets the job done pretty well. I bet that sooner or later it could be embedded into KDE (or your favorite window manager).
