Thank you for the above reply.
The Preview screen was there after the fix but it was not a "Re-Appear" as I don't know if it was missing before the fix.
I was checking if EMC10 had a Preview Screen when the app would not let EMC10 start because the drives were not available.
As for trying the Fix on my Win10 machine, I hesitate because I have 2 Roxio Apps there and I don't know which one(s) it would affect. I may yet try it.
My XP machine (EMC10) has 2 DVD drives that can play Music CDs but cannot play a DVD Movie. Device Manager says they both have the best available drivers and are Enabled.
The DVDs show the Movie title and using "Open" shows the Movie files but they won't play with VLC; an error occurs.
Anywho, that's life with computers. I've been doing PCs for 40 years (70s), starting with Sinclair, Commodore, TI and then IBM type. I've seen a lot of problems.
