You know, I just mount my Myth NFS share in Windows XP and use Tsunami
MPEG's DVDAuthor to grab 4 .nuv's (Or .mpg's as the newer svn versions
are correctly naming them) which have been recorded in 720x480 from
one of my PVR250's, and creating an image (And burning) them directly.

It's even good enough to cut out the commercials (Using a GOP-Editor),
though admittedly I do have to do that by hand before authoring.
