For some time I've had a problem burning my recorded TV shows onto DVD. The symptoms seemed to be inconsistent, but it appared that when I didn't have to transcode any files (i.e. content was about 60 minutes) then the burn always worked. As soon as the content was more than 60 minutes, the burn would fail during the last part of the DVD write.
After numerous attempts at trying to fix this, it turns out to be a problem with DVD+RW (Philips media) disks I was using and my DVD re-writer (DVDRW IDE 16x).
I think that the DVDs are not correctly erased after using them once. The first time I used them, they would work fine. The second time (after erasing in MCE), the burn would always fail when the content was more than 60 minutes.
As soon as I moved to using DVD-RW disks (Verbatim), I've not had any problems.
Has anyone else seen any similar behaviour?
