The best is to use the driver linked here (Pinnacle 64bit).
To quote: I've modded the Beta 64-bit drivers to work with the PlayTV too. I've only tested it on Windows 7 x64 but it should work fine under Vista x64 too.
Windows Media Center detects both tuners and works perfectly under Windows 7 x64 build 7000. Same procedure as Gringo.
- Overwrite the original PCTVDIB64.INF inside the Archive.
- Plug the PlayTV and load the Driver.
