I have (not) had great fun with my Pioneer DVR-A04 lately. I read about the problem with latest 4x disks and decided to up the firmware - originally to genuine 1.31 then to every variable I could find just so as to get the drive to write constantly with various programs (Nero/RecordNowMax/InstantCopy). After weeks of messing around (as well as filling our kitchen cupboards with loads of coasters), I finally ended up with v1.33. Now the problem lies with the fact it doesn't want to play ball with DVD-RW disks! Yes I forgot a couple of times about the 2x situation and unfortunately killed those, but even at 1x all programs just spit the others out at lead-in. Any advice out there?
