Windows 7: WMC Setup - Upgraded from Vista Premium

WMC Setup - Upgraded from Vista Premium

Going through an upgrade to Windows 7 (Ultimate x64 from Vista Home Premium x64) and saved the media center setup for last before I move my files back to the original locations. However, I am having problems with the TV setup. I think I may know the source of the issue, but wanted to confer with people much smarter than myself who may point me in the right direction or had this experience.

I have made no hardware changed during the upgrade and have been using the Hauppague 2250 WIN TV HVR-2250. I reinstalled the WMC specific drivers for Widows 7 and went through the process, and to summarize, no go. Setup manually and went to a channel to check this and got the message "Files needed to display video are not installed or are not working correctly. Restart Windows Media Center or restart computer."

I am just connecting the OTA antenna and pulling the local digital signals (no cable) so it is just limited to that signal. Here is where I think the problem may have originated.

During the setup, I relocated all default user profile directories to another partition (away from the standard system drive) through the registry. I am assuming that doing this, I moved the file location where the source file is directed to this partition and WMC is still looking in the "default" location for the video source so I will need to edit the registry to change the default location to the new user profile location.

How I drew this conclusion:
I went ahead and installed WinTV v.7 because i wanted to record some old VCR footage through the s-video connection. Was having similar problems where the program was reverting to the default location (the "C" drive), and it was not picking up the TV signal. I changed the default location (to locate the "buffer" and "data" file in the program to the new user location and that straightened everything out for that program. So the assumption is that WMC is experiencing the same problem and i need to modify the default location in the registry to redirect WMC.

So finally the questions:
1. Are there multiple registry edits that need modified or is there a single location where these edits need to take place.
2. Since you do not have an option to edit directly in WMC, if I make these changes in the registry, reboot & restart the WMC setup process, will the setup process automatically revert to the original ("C" drive) location or will these changes hold through the setup process and I can go through the automatic setup process without problems. (Or do i have to go with the manual process).

sorry for the lengthly explanation, but hopefully, I provided a little background on my major "tweaks" that can help diagnose the problem area.

As I suspected, my assumption was correct and a modification of the default directory in the registry for WMC did solve it. While it did not complete an automatic install, the channels did auto-populate and when I when to Live TV, there was indeed a signal. However, I have yet to do any recording at this time so we shall see.
