I have no solution to this except to toss Easy CD/DVD Creator out the window and use other programs. I wasted 4 hours on this.
****UPDATE****
I stumbled on one of these messages (can't find it now) that gave me the solution to all of this. Roxio has developed an engine update that fixes the problem. You first remove the filters in the Registry (referenced above), then install the engine update. The update says it applies to Version 7 adn above, but others found that it also applied to older versions. The update is the file pxengine4_10_28a.exe. If you can easily find it on the Roxio site you are a better person than I! The Search function on this site leaves a lot to be desired.
Anyway, the update fixes the SP3 disk disappearance problem.
