This should help, I copied the below advice off here a while ago, and rather preach about the Search button it's easier for me to paste it here - I can't remember who posted it but thanks again

---No problem. Currently, as you have correctly noticed, there are no creative drivers for the DXR3 card. However, the card is really a rebadged Sigma Designs Hollywood Plus. TO get the card to work, you need to do the following:
1. Go to the Sigma Designs website (
http://www.sigmadesigns.com). From here download the latest beta drivers for the hollywood plus board. (you'll find them under the hyperlink that discusses Windows 2000 drivers on the home page). Just download the drivers - no the DVD player application - it won't work!
2. Go to the Creative labs webpage (
http://www.creativelabs.com) and download the latest DXR3 drivers for Windows NT.
3. Install the Sigma designs drivers. DO this by unpacing the driver zip file into a directory on you hand disk, then go into device manager, select the DXR3 card (it will show up as unknown multimedia card or something like that, You'll most likely notice it by the yellow exclamation mark next to it.) and then point Windows in the direction of the directory containing the unpacked drivers you just made.
4. Unpack the NT application and Drivers for the DXR3 card. Install the DXR3 player application by running setup as normal. The player should install without hitch - however, if it complains about being unable to detect the card, you'll have to go back to the Creative site, download the DXR2 drivers for NT and install just the DXR2 application. The DXR2 application doesn't check for the presence of a card. After this, you should be able to install the DXR3 application - it will detect the DXR2 software, and assume that because of this you have a DXR3 card - strange but true. Once the application is installed, tell Windows that you don't want to reboot.
5. Finally run the program that installs the NT drivers for the DXR3 decoder card. They won't actually work, and won't even install because of the presence of the Hollywood Plus (you won't see any messages to that effect) - however, these drivers make some alterarions to the regisatry that allow the Creative DXR3 player to function without frequent crashes and choppy sound.
6. Reboot.
7. Congratulations - if all has gone well, you should be able to use your DXR3 card. If you have any problems, this procedure can be found at
http://www.driverguide.com in the creative labs driver discussion board.
Hope this helps
