PVR-TV BDA Driver(PVR-TV 300U/PVR-TV 305U)

HyperMedia Center Software

Download your Driver first, and install. Then you can download the HyperMedia software for your TV Tuner, if you like. Both are compatible with Windows 7, Vista, and XP, 32-bit and 64-bit.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514
