I,ve the same problem with Philips CDD4801.
It hangs when writing the lead out and then just stops.
Nero just keeps counting and hangs too.
After manualy shutting down,my rewriter can`t read or write anymore.
I,wanna try this firmware update but I,don`t know how to.
Is there a tutorial somewhere?
My current Firmware version is C2.1.
Greetz.
