HELP! dvr-104 won't burn!

I recently acquired a Pioneer DVR-104 from a friend's Quicksilver G4 and installed in my MDD G4. The drive worked fine but since 2X is a little hard to come by I opted for the patch to enable it to burn 2X on 4X media. The drive revision is already A227 and the patch I d/l was version 1.40. After patching the drive it is unable to recognize CD-R and DVD-R media (showing an icon on the desktop) and through Toast 6.0.5 I managed to start a burn but got an error about buffering 1/3 the way through. Funny thing is that after the burn the drive recognized the badly burned disc but was still unable to see blank ones. Anyone know what to do or have just acquired a new doorstop?

When you say patch, do you mean a firmware patch?

Also you can put faster media in the drive. You just have to burn it at the slower rate.

yes it was a firmware patch. I was trying to get a full 2X with existing 4X media. Now I'm trying to figure out why it doesn't like DVD-Rs now.

Your problem maybe due the patch you just installed. I don't know to much about firmware patches, except for what have read. I know there is warning, that if a firmware update goes in wrong. You will have more problems.

You might want to do more research on the firmware update you installed. Is ut Apple supported? Can you re-install it or down grade it? These are some of the questions, you may want to check into.

On the patch it gives three options of 1. region-locked A227 revision (which I had), 2. X227 region-free, and 3. version 1.40, ability to burn 2X on 4X media (which I chose). I've tried to repatch with the first option but nothing changed. There was a disclaimer but I'm still hopeful of any solutions that could at least get the drive in working order again.
