For others that may be interested: there is an opensource driver for bt878 called btwincap that comes in both x86 and x64 flavors and works in Vista and 7. Also DScaler knows how to operate the device physically but it tends to be unstable. However, WHM btwincap with DScaler make a good match.

- Go to WDM Video Capture Driver (32 bit) or google around for x64 version (PM me if you can't find it)
- Install WDM driver
- Get any WDM-enabled tuner app (like DScaler)
- You're good to go
