I use 3 budget dvb cards with no problems recording 3 streams and watch ing
one of them while recoding. I think also hd recording can be done with this
cards, because the data is not decoded by the card and so hd is only a strem
with a higher bitrate.

I just dropped a PVR-150 into my MythTV machine here, to go along-side of
two PVR-250s that were in it already. Several times a week we've got all
three of them recording, while -also- watching something that we'd
Funnier yet, I -know- that my box is a bit underpowered; its a 1GHz Athlon,
640MB RAM, runs on a single 200GB WD driver on ATA-100, and uses an Nvidia
Geforce4 MX 4000 board for the TV-Out. NOT the beefiest of boxes, but I
my wife) have been quite happy with it.
We did have a few ivtv driver related issues when I put the PVR-150 in it,
I'm hoping that ivtv-0.4.0 resolved the drop-outs we were getting (if not,
I'm sure I'll be in the dog house again).
Quality wise, all three boards are recording at the default MythTV settings;
can't remember going in and twiddling them when I installed the machine.
If you're planning on recording multiple streams, do yourself the favour and
get a board that does hardware MPEG encoding. CPU usage on this machine is
~5% when recording 1 stream. I haven't checked on it when we're recording 3
streams and watching a recording, but it hasn't choked on us yet. :)
