[mythtv-users] Is my p3-700 fast enough for a wintv capture card?

	If you've got a video card that supports Xv, you might make it go at
reduced quality, but it's marginal.  I've got a dual PIII-933 currently that
can record/play from a bttv-based card.  I used to use a dual Celeron 300->450
that was capable of recording/playing at the same time at 352x480 rtjpeg.... 
but it took 90-95% of one cpu to do that, and another 50%+30% (split between 
mythfrontend and X) to play it... pretty marginal, but fairly watchable.

	Bottom line.... the PVR-[23]50 is *much* friendlier.... I doubt you'll 
regret switching for $100.  Once you find a faster machine (or make a slave 
backend with the PIII for *only* recording with the bttv), you can have two 
cards.

I installed the card and drivers and got everything working for the most part, but the video is choppy, and watching live tv takes 100% of my CPU at the default compression settings.
