I have the above writer which has firmware GS0P.

Just recently I've found a couple of commercial DVDs that ANYDVD said it couldn't read and that CloneDVD reported CRC errors on. This happened even after cleaning.

If I transfer the DVDs to my other writer
PIONEER DVD-RW DVR108 firmware 1.18 they are OK.

I wondered if it needed a firmware upgrade but I've looked at the LITEON site and as far as I can see there isn't a later firmware upgrade.

Was just wondering if anyone could offer help/advice as to what the problem might be as the LITEON write seems to be OK in all other respects as far as I can tell.

Thanks
