Which DualTV software package should I use for WinXP, Vista x86, and Vista x64?
If you are a WinXP user, please use v1.34 package (downloadable at http://www.nvidia.com/object/dualtv_full_1.34.html).
If you have a new Vista PC or a PC with fresh install of Vista, please use the v2.02 package (http://www.nvidia.com/object/dualtv_winvista_x86_2.02.html for Vista x86, and http://www.nvidia.com/object/dualtv_winvista_x64_2.02.html for Vista x64).
If you are upgrading a WinXP PC (with DualTV installed) to Vista, you may see the v184.108.40.206 DualTV driver from Windows Update. You can install this driver from there. However, the DualTV Vista/MCE extension is not available at Windows Update. NVIDIA recommends that you download v2.02 DualTV software from http://www.nvidia.com/content/drivers/drivers.asp and install this package instead.
Note that v2.02 package for Vista, which includes v220.127.116.11 driver, obsoletes the v18.104.22.168 beta driver for Vista.
