Incd and AVG and Blue Screen

Win Xp Home system.

Ran Ccleaner, Ran Ad-Aware SE personal, Ran AVG scan, ran Checkdisk, ran defrag, Uninstalled INcd in Safe Mode, reinstalled latest InCd.

Each time I run Windows backup (NTBACKUP.MSI), burning to a DVD-RW, it gets to that last action of backup it goes directly to a Blue Screen saying AVGcore.exe is a problem. If I backup to a hardisk there is no problem.

I assume that INcd is the problem?

Can anyone please advise?

Additional information. The burner is a Philips DVD8631. Windows cannot find a more uptodate driver than that installed.

Found that in another identical machine replacing the Philips DVD8631 was the only solution!
