[mythtv-users] How much horespower for frontend?

[Jason]

hmm. man I'm really at a loss. I have done a lot more work with a lot
less hardware then you are running right now and have had no issues at
all, so Im realy fairly perplexed. This may actually end up coming down
th PCI video, but I have  a hard time with that since my Epia 800Mhz
board works  very well as a front end.

The place where you made your stand never mattered,
