1. Get the 2.6.12 kernel from kernel.org and accept no substitutes. Only
2.6.12 without any rev numbers on the end. This is the link:
2. Compile it.
3. Check the numbers on your /dev/dvb/adapter0 goodies. If they're not
212, run the includeded MAKEDEV-DVB.sh script.
4. Make sure the line "options bttv i2c_hw=1 card=0x71" is in
5. When loading the modules use 'modprobe dst' followed by 'modprobe
With any luck at all, you'll have more hair than I did after it's all
said and done. This should work. If it does, you can play with using the
CSV on linuxtv.org and maybe the patches to bring your kernel up to

Micro$haft puts out. :^)
