Before Windows XP-Home Re-install: I could burn and play any DVD. I was successful in using Pgc-edit and producing dual-layer DVDs. After performing XP-Home Re-install due to major OS foul-ups: The computer shuts-down after inserting any copy protected DVD. The monitor displays a blue screen and suggests running a system diagnostic utility, a memory check, and faulty memory. Also it says to try changing video adapters. I can insert un-protected DVDs without this problem but I can't get them to play. I have a Dell 8300. Sony dual layer DVD/rw (after market installed), Nero has been un-installed, reinstalled, uninstalled reinstalled, Windows media player 10 with intervideo plugin. Do I need to remove the dvd burner, reboot, reinstall the dvd burner and reboot? It seems that it is a software issue.
