Thanks for the heads-up, Troubleman.
So far, the drive is SWEET!! Installation went without any problems at all. I also updated the firmware to BSLB last night and I've been happily burning CDRs and DVD+RWs. Really amazed at the speed and stability.
I've also learned that my Princo DVD-Rs are, well, worthless (probably ALL my problems with the Pioneer drive came from the fact I was using this bad media, but, hey, I'm glad that made me upgrade the drive!).
Really, really happy with the features of DVD+RW (being able to multisession the discs is great!!)
Next up: reinstall the Pioneer drive into Bay 1 (contains a Lite-On CDROM right now) and see if I can get true DVD to DVD copying going.
I'll keep you all updated. Thanks again from this Newbie!!
