hardware mpeg encoders with Linux

[Ralf Haller <ralf@xxxxxxx>]

Hi again,

I am trying to build a digital vcr using my old AMD-K6-2 box running 
RedHat 8.0. While testing some software encoders (mencoder, mythtv) I 
figured out my system is too slow for realtime encoding.

Can I use hardware mpeg encoders like Pinnacle's PVTVpro or Hauppauge's 
PVR-250 (?) for building such a system with Linux? Are there any drivers 
for these cards?

Buying such a card will be much cheaper than buing a new computer.

Thanks for any help,

r@xxx
