Aye, yeah all disks (i've tried about 20) work with every other cd / dvd drive that i have tried.
There seems to be a difference between if they are proper issue (windows installation disks) and other homemade ones).
I wasn't sure if it was one of these Sony anti-pirating small progs that they instal and hide on computers to allow only certified (?) disks to work/ But i downloaded some small prog to search for the Sony bug - and it didn't comeup with anything.
