I have one that's been going for maybe 1.5-2 years now. It's a 1.8GHz
Celeron with 512 MB of RAM. It's running Debian unstable, as that's the
developers' platform. Started out with a cheap WinTV Go card, but
upgraded to the PVR-250 a year or so ago and didn't look back. (The
cheap card is in a more-powerful machine that also does other things, as
a "Tuner #2" backend). It was fun explaining to a friend for whom I was
captuing some camcorder video that my video capture tool was "cat".
The video card is a GeForce440mumble with TV out, though the TV out
doesn't quite fill the screen despite fiddling with the TVOverscan
option in XF86Config-4. The machine so far has handled everything, but
the UI gets slow if it's playing back and recording and trying to do
something else in the background (like transcode).
I'm using the PVR-250's remote, no problems. The only problem I've had
is that the PVR-250 will sometime end up recording with vertical "lines"
in the output. This is a firmware bug - switching inputs fixes it, so I
have cron switch inputs then switch back daily at oh-dark-thirty - no
You'll want to run (s)ntpd - in the beginning, I learned the hard way
that your machine needs to have a good idea of what time it is!
I thought about using wireless, but it'd have to be good wireless
because you'll be throwing around files that are 2GB / hour. I broke
down, drilled a hole in the floor and ran Ethernet to the machine room
(but my wireless is only 802.11b).
I just added an ugly, but functional IR blaster to this to control my
TWC cable box. MythTV 0.17 is smart enough to know about different
channel lineups connected to different inputs on the same card. I took
the analog channels out of the Video-In lineup because I get better
reception through the PVR-250's tuner that through capturing the
video-out of those channels from the cable box.
