Hello,
Thanks for all the help.
I ran dxdiag and it said I had version 9.0c of directx. Then I downloaded dxwebsetup.exe and when I ran it to install, it confirmed I had version 9.0c or an equivalent, so I did not need an update, already have the latest version.
So, I can't blame any problems with EMC 9 on directx. I have gotten most of it to work properly, but still can only burn Music DVDs by creating an image file and burning that file to a DVD. The burn never completes when I try to burn directly to DVD from the project window. Also, still can't get the add audio and import from DVD to work in Music Disc Creator. My work around is to use drag and drop. Interestingly, the add audio and import from DVD work in the DVD Music Assistant application.
But, on a good note so far everything else I have tried is now working. At one point I think almost the whole program was broken. I have done 2 clean installs and used RegCure to get to this point.
Thanks again---

UPDATE: PROBLEM FIXED
First I did another clean install. This fixed all the problems, except the media selection window not opening in Music Disc Creator. After exploring jeanrosenfeld's tip
here, I began looking around in the registry. I thought, well the media selection window opens in DVD Music Assistant so I will compare the entries in the registry.
Opened the registry by doing run - regedit - ok
navigated to the proper register entries by clicking the pluses:
HKEY_CURRENT_USER
Software
Roxio
emc9
MusicDiscCreator
MediaSelector
WindowRect (in the left hand window) values were 1213,390,600,480
I compared these values with the register entries here:
HKEY_CURRENT_USER
Software
Roxio
emc9
DVDMusicAssistant
MediaSelector
WindowRect (in the left hand window) it's values were 100,100,606,480
So, I modified the values in MusicDiscCreator - WindowRect to 100,100,606,480
Exited regedit, did a restart, and presto, when I click Add Audio Tracks and Import From CD/DVD the media selector window opened just fine.
Only problem left is not being able to burn a DVD directly from the Music Disc Creator window. Still working on that problem, but am able to burn what I want by making a disc image of the project and burning the image to DVD.
Thanks
