Could be that my Panny was more discriminating than the Mags. I wonder if there is a difference between just burning and not finalizing and then erasing the titles versus burning, finalizing and reformatting?
In any event I only use the -RWs to transfer programming from my DVR downstairs to my upstairs TV. If there some minor problems it's no biggie. I'll probably just run the discs into the ground.

What I found is that after 15-20 burns the -RW would start to fail the verify cycle. It still burned without issue and without an error, but it failed the verify. Once it reported a failed verify, there was no turning back -- the -RW was toast. To test, I tried repeatedly re-burning the image or burning a different image to the disks and the verify errors only persisted and got worse.
And through all of this, the actual erase/burn process never failed or issued an error.
I never kept a DVD-RW disk around long enough to see if it would eventually fail during the burn cycle. I bought them in bulk packs and tossed them as soon as the verify errors started. The errors generally started around 15-20 burns. So by the time you hit the point where the disk won't format, it's a pretty bad disk and has been for a while.
