I did a little experiment today, described below.
BBC HD, BBC ONE HD and bbcs and itvs (non-hd) satellite channels are
back on my cheap what is it 60 cm dish and nore than half a decade used
super cheap receiver antenna! I suppose the "rationalisation" that led
to (too) weak signal except for ITV-High Definition by limiting the
"footprint" of the satellite transmitter cones is over or ended in
letting me share the great BBC HIGH DEFINITION channels on the media
machine with old !) meter sat cable still on it..
I often view on the I7 machine with the GT430 cards' VDPAU h264-,
decoding- and inter-frame filter capacities, though the upgraded
pentium-D with 9500 card is fine too. The signal passed live to the
server over 1Gig (or actually 100baseT because the upgraded pci network
card in the media machine somehow interferes with the sat card a bit)
done with the fast I7 can be stunning at times, given the right
filter settings and the beeb encoders doing their work properly.
Complicated music (re-)mastering setups with linux in 192 kHz
To drive these 192KSample/sec. signal processing blocks, it is possible
to get a pretty good sample conversion by using -q 3 parameter with
alsa_in (from recent Alsa tools) or similarly with Mplayer filter:
sounds very good and neutral, and its nice to have 8 channels of
DA-converters with -90dB harmonic distortion on the server and even 2
on the cheap but good I7 notebook. These can go directly into the
preamp of my main audio system or the powered monitors I made, for
RF sinks and sources
I think there are dozens around.

Rock voice and HD vid of me playing some harmonized Kurzweil PC3
Only the digital output of the synth was used, and only (live) sample
converted from 24 bit 48kHz to 32 bit floating point 192kHz.
Here's the same in quality enough 256kbps audio: harmo5.mp3 (26 MB).
Screen dumps from the I7 server (Running Fedora 14/64 bit Linux)
showing harmonizing voice processing setup (the synth wasn't receiving
more effect than ONLY some added Lexicon reverberation):
automatically generated jack signal connection graph.
The jamin effect is FFT-based (pretty high quality library), and is
mixed with a delayed signal for harmonizing the voice (mine) in the
recording, in this case in a fixed manner (unchanging throughout the
recording)., and I could hear the result live while recording.
