I've been having similar problems with ripping dvds into MythTV. I think that it has to do with a transcode problem, although transcode is installed. When I rip a dvd as an ISO or as "Perfect" quality it works. But when I rip a DVD with any lower quality options like "Good" or "Excellent" it goes through the ripping portion and stops. I can see the file did rip into /var/lib/mythdvd/temp/, but after it stops the file is deleted. I've attached the mtd.log file from these transcodings.
