I see from other posts that several people have had the same problem : Namely my G4 MDD will not recognise the DVDs I burn on my G4 laptop using the Superdrive. The installed Combo drive on my desktop machine is a Phillips CDD5101 with revision A3.5. I believe it is possible / advisable (?) to update the firmware but can't find a download location. The only locations I've found are support sites for PCs and I feel the firmware may then cause me more problems than I have already. Thoughts anyone ??
