Wasn't sure where to post this, so I'll post it in here But ever since I got my first DVD recorder (which broke) then got my second DVD recorder made by cheap-n-cheerful Techwood, I've noticed there has been a very high failure rate of discs being verified on ImgBurn once they have been finalised on multiple DVD burners. Even though the discs themselves may play back in different players.
So I've come to the conclusion there are a number of factors of why I'm getting the failures.
The discs are genuinely failing to verify from poor burns (e.g. DVD recorders always burn at 1x, and modern day recordable DVDs aren't meant to be burned at such a low speed) or doesn't work with the disc blocking information (e.g. DVD recorder burner [see below])
The MID codes I am using aren't meant to work with the firmware (see below)
The Macrovision encoded is preventing me from reading the discs correctly.
I somehow think that the Macrovision is preventing me from making copies. (Macrovision 7.1). Although it doesn't explain why I can copy some discs, and not others?
The MID code for the discs are Ritek F1 / RitekF16. Some of these discs are getting mysterious blue streaks on them, as though they are scratched before being recorded on. The standalone firmware on the DVD recorder is DVSKOREA DRL-200.
Why do I have so many failures? What is the cause for so many failures? Using my PC burner, I always get a good burn, but in the standalone? Forget it.
Any suggestions? I know Macrovision have a nasty tendency to fill an area with "junk" data to prevent discs from being copied. But even recovery software might not recover such information - Any ideas?
