Hi Jeff Smith:
___WinDVD and TheaterTek can interfere with each other but Andrew (coder of TheaterTek) placed a check for default filters in your configuration menu just to make sure you don’t start up TheaterTek with the WinDVD DirectShow filters intact. Once you use TheaterTek for about 10 seconds, WinDVD 2000 ver. All - 3.2.xx will be a distant memory although I still install it just in case … PowerDVD on the other hand will not screw with TheaterTek’s DirectShow implementation that I have seen so you are Ok there.
___As far as registering it, it is a long one but just install the player. I am sure you have already been through this a few times but just in case.
___You may only have the 1.0.048 version disc. If so, before launching the player, upgrade it in the order the patches were released. Apply 1.1, than 1.1 - 1.1.1, and 1.1.1 to 1.2. It will have you reboot in the install sequence a few times. Afterwards, launch the player. A registration splash screen will pop up where you insert your initial serial number and pass code. From the front of the TheaterTek disc. When you launch TheaterTek for the second time, you will receive the final registration passcode screen with an 8-digit key that you must send off to Andrew at TheaterTek.
___I format the registrations similar to below but if your HTPC is connected to the Internet and has an E-Mail client installed and setup, you can use the E-Mail method built within TheaterTek to pick up the registration code directly …
