thrunner has made a good point. If you take a 5005 recorded disc and run it through cd/dvd speed in Nero, you'll see a wacky read curve after around 60% or so.
With cheap media (TEON MCC and TDK CMC ) i frequently get read errors towards the end of the recording that other DVD players can't handle. So now I pretty much only use TY+R and either Fuji+rw or Imation+RW. Never a problem with those. And for stuff I want to archive, I do all my editing etc on the computer, in any case, to avoid hassles with compatibility on other DVD players.
That being said, I also haven't had the stopping problem in either OTR or AV1 or OTR using AV1 even with the cheap media.
