I also had this problem. I've turned off automatic transcoding, and now
transcode programs manually after watching them, if I want to keep them. I've
not watched all of them again, but I've not spotted a file that was received
without corruption to then be corrupted by transcoding.
Mind you, I've never received any DVB that's been too corrupt to watch either.
