Thread: NVIDIA XcVM support . . . . does the card model matter much?
NVIDIA XcVM support . . . . does the card model matter much?

Currently, I'm running myth .21 on a combined
frontend/backend. The host is a nice quiet HP mini tower
with a P4 1.8 Ghz cpu and 768mb of memory. (Found it in a
dumpster . . . go figure)  It does just great as a SD
capture box, but now that I have an HDTV I'm starting to set
my sights higher.

I have a PCHDTV-3000 card installed, and (just recently)
finally got it working. I haven't worked out all the channel
mappings yet, but I manually scheduled the capture of half
an episode of Malcolm in the Middle and it completed OK.
Played with my standard playback mode, the video barely
plays.

So, I'm looking into either

A) enable XcVM on my GeForce FX 5200 card, and hope there's
just enough cycles to play HD  768 mode, or 

B) turn my current system into a backend, and put together a
powerful but slim front end.

In the latter case . . . does it much matter which NVIDIA
based card I get, if all I'd be using it for is HD playback?
Some of the lower end cards don't have a fan, for example,
which should reduce noise and power usage.

You may be able to get it to play. ; When i first started testing MythTV on a old box I got HD to play on a Athlon XP 1800+ (1.5Ghz)  But the issue was when it would skip comm. or OSD would appear forget it.  You had to wait 20 sec for the sytem to recover. 




B) turn my current system into a backend, and put together a powerful but slim front end.

Not much. ; the 5200 and 6200 are by far the most popular.

the 5200 does support XvMC - it might be capable of HD768 -
give it a pin.

Yes. Contrary to popular opinion not all NVIDA cards support
xvmc playback. 
The 6100 doesn't, the 6150 does. Unfortunately I know of no
list that tells 
you ...

Apparently none of the 8xxx cards do:
