Strange. I'm having the opposite problem. Hard time formatting my +RW discs with v0457. I usually have to reboot at least once after the format attempt to get Roxio or DVDInfoPro to see the drive again. Also, the drive kept reverting to PIO mode with 0457. When I get past that, they seem to burn OK. With 0357, none of that happens.
I wonder if something corrupted during my FW update. I've never had a problem with any of the updates before. I'll try re-installing 0457.
I wish I knew what changed between 0357 and 0457 (or any of the updates for that matter).
