Thank you both for your answers, that makes more sense now.

I've got 2 very underpowered frontends (either Celeron 433s or P!!! 
667s) I don't think the i810 drivers can off load enough for smooth SDTV 
/ DVD playback (I know my GeForce 2s wont) so I'll probably get a couple 
of GeForce 5200s to enable these venerable old PC to be reborn as frontends.

I have a few 250MB Radeon 9250s for when the OS driver for them supports 
XvMC, (joy of joys, I'll have a pure system) but I'm not holding my 
breath and it remains to be seen weather my Athlon XP 3200s with full 
XvMC and any other support I can give it will do HD h.264, probably not 
but we'll see.

Thanks.

Don't know....
I'm midway through a game of musical computers....
now, which one is going to be my Smoothwall....
you, you could be my Astrisk box....
but then I've only got one MythTV frontend....
I'm going to get more old computers, they're such fun.
