I own a Sony VAIO (VGN-AR21S running XP) laptop with the Matshita UJ-210S blu-ray drive. I recently downloaded a 1.06 firmware upgrade from Sony. Since the upgrade however it refuses to read Pressed Data DVDs and more importantly Blu Ray. It does however read CDs and DVDR.
I am at a complete loss so far with Sony, and found only one mention elsewhere of a similar problem (but with no detailed followup). Does anyone know how to remedy this problem, perhaps by downgrading the firmware back to 1.05.
Would appreciate any help on this matter.
