Burning disc but not closing it synonym to malfunction?

Hi,

My Matshita UJ-845D (firmware D100) successfully burns DVD+Rs (panasonic) but ony rarely gets to close the disc or session without throwing an error (0xeb020b8a err_code.)

I’ve never had this issue before and, the truth is, I’ve never used media from Panasonic – was using cheap brands.

Seeing the drive is able to burn the data onto the disc, what do you make of the fact that it can’t close the session or disc? Do you think it is malfunctioning even though it burns 4GB of data? Could this be some kind of media incompatibility?

Does anyone know of a site where I could get the latest firmware for the drive?

Thank you.
