This site ROCKS!
Thanks for the help guys.
Don't have the Pioneer yet, doing my research first. I have a set top Pioneer DVD, that I love, and it came out of the box all-zone enabled - very decent! BTW, my "supplier's" tech support claim the 107D has proven to be more reliable than the Liteon and Sony.
I confess, I use Roxio 5 :o . Got it free and I liked it for DirectCD. Annoyingly, as reported on Packet writing elsewhere here, it has just started playing up and I can only do reliable burns of my data via a data project now . XP burning also started playing up at the same time.
So - going off topic for a bit - I've followed advice here and cleaned my lens, "disabled" XP burning and checked IMAPI (same thing?). Admittedly, my burner is not set as a master (Ricoh MP7400A - was I the only person to buy one?), but it worked OK like that before. No joy.
Interestingly, I just recalled yesterday that the last bit of new S/W I installed was Creative Playcentre with my Audigy, and I discovered at the same time it has audio burning S/W too - I've never used it - I wonder???
Also would have recent BIOS updates for my Asus P4B and Asus GeForce 2 MX400, will check on that one day.
