I am using a Pioneer 105 with 1.21 firmware, running XPPro with SP1. I have so far had very mixed results with a combination of dvd-r media and burning utilities. I have had absolutely no problem with Ritek 4x discs. They work fine with any method of dvd ripping, iso's etc and using dvddecrypter, nero and instant disc to burn them. The same can be said about Verbatim dvd-rw discs. I have been unable to successfully burn a movie to dvd using Datawrite "yellows". The dvd always corrupts near the end of the film and sometimes in the middle. This is strange because from reading this forum most people have had no trouble with these discs. I have just bought some Datasafe 2x media and I have only been able to burn a movie using Nero which according to a lot of people is crap at burning dvd's. All of the other progs I have tried have failed with these discs. Is this easily explained or have I just come across a duff batch of discs? I am going to get hold of a copy of Prassi or RecordNow but as the burning techniques I have used work with the Ritek discs and dvd-rw's I don't understand why they shouldn't work with the cheaper media other than it is poor quality. Any comments would be appreciated.
