bt878 based cards are not easy to get running, especially with vendor 
kernels (see below).

You are using a Mandrake "vendor kernel", right?

It seems that Mandrake patched their 2.4 kernel to include some version 
of Video4Linux-2 support. The Avemedia bt878 driver needs a recent 
version of the bttv Video4Linux-2 driver. Because of the fact that the 
version in the kernel is too old, the DVB driver fails to compile.

Make sure no bttv driver gets compiled and there is no bttv installed in 
/lib/modules/<your kernel>/.

Install the bttv driver from the "video4linux" package, then compile and 
install the dvb driver. "modprobe -ae" will show you if all symbols from 
all modules are satisied. If so, you can load the drivers.

The firmware is for Technotrend/Siemens/Hauppauge DVB cards only, you 
don't need it.

Use 2.6.5, apply the patches from the "patches-2.6" directory. It's much 
easier to get going.
