The Brooktree Bt848 TV-Card

So I got this (for me) unknown PCI TV-Card. Since I have got no more free PCI slots in my Linux machines, this one was to go in a Windows 2000 PC. And that is pretty much where the problems started... ;-)

With no really useful text on the card, I used a Debian rescue disk in order to find the card report itself as "Brooktree Bt848". My card has the very common Philips FM1216 TV tuner, and in combination with a lot of googl:ing I found a lot of useful, and a lot of less useful info on this. Finally I found some drivers and got the picture (both actually and literally), but no sound. So I made this page and asked the people in alt.comp.hardware.pc-homebuilt for help. I got help:

Bt8xx WDM video adquisition Driver

With this driver, I got it all, sound and picture. I also got indications that my card is perhaps a Leadtek WinView 601, but I am not quite sure. At least, that is what I chose when installing the drivers from the link above, and it works.

Still, there is the choice of TV application to be made. I currently use BorgTV, but it will not let other programs access the audio out when running, which is quite disturbing.

The reason for doing this page is since I had a lot of problems to make it work, I might help some other people out there. Below I have an image of my card along with descriptions of the different circuits.
