I just removed ver 8.0 of Roxio due to its lack of compressing dual layer DVD to single layer. After removal and reinstall of ver 7.5, I lost access to both CD/DVD drives. The fix is per MS Knowledge base article 314060 and requires a simple registry edit:
I am starting a new thread with this fix, as I spent 4 hrs of various forum fixes including roxiozap and windows config utility and Sonic engine updates before finding this EASY fix. This knowledge base article really works, so I am hoping this new thread saves someone else the aggravation. I suspect many will be trashing ver 8.0!!
