No, the driver for the NVTV single and dual tuner cards are not compatible with Windows Vista. The NVTV tuner cards were manufactured and sold by third parties, based on the board design and driver provided by NVIDIA. NVIDIA has no plans to update the drivers. If you are interested in a high-quality dual-analog TV tuner, take a look at the NVIDIA DualTV MCE tuner card, made by NVIDIA and available from the NVIDIA Store. A Vista driver for DualTV is available now.
