Well as you know chef, I got lucky and the DVRupdate worked. I had to copy and paste the flash files into the same folder as DVRupdate. This whole process needs a checklist with PNG pics. The zip files when unzipped load in their own locations(when you double click on the zip file) and you have to go look for them. Not for the novice on computers to say the least and Pioneer expects the average customer to figure this all out on his own. Not! The Pioneer forum was actually pretty good(explained the Intel MOBO issues), but I did not find it until after I figured it out. I still think Pioneer makes great products and the 109 reflashed is a great product. Just all those flash issues are a irritation and fun all at the same time(I know, I need to get a life). Plex/Nec/Aopen/etc have no brainer flashers that work on Intel MOBOs and XP without a hitch.
PS//buy one anyway, at $49 shipped at newegg.com it is a steal and may be the best all around burner on the market after a crossflash to A09FW.
