Got lost in the threading, so replied to the original message :-)
I have a core2duo frontend (Antec Media CAse) running trunk, with a
core2duo e2100
As ffmpeg decoding is effectively single threaded my 1.6 GHz dual core
is just not quite good enough for BBC-HD. With a little patching [
http://svn.mythtv.org/trac/ticket/4653 ] it uses both cores and all is
well . Thats why I keep trying to get the devs to include the patch for
it ( ;-) ).
I have a 6200 silent NVIDIA card on the frontend, which I had been using
over S-VIDEO, as I have a CRT interlaced TV.
I have recently moved to using a VGA-SCART cable, and custom modelines,
so delivery is straight interlaced content to the TV. So despite having
a perfectly working frontend .....
I have just bought a Aspire Revo, and been playing with it this weekend.
To avoid the confusion further down the thread there are 2 Linux
versions floating about:
ebuyer etc have :
92.G1DYZ.UI0 which is Linux, Single core 230 Atom, 1GB RAM, 160GB HD, no
SPDIF. £150 delivered
A few smaller places are selling small quantities of:
92.NVDYZ.UI0 which is Linux, Dual core 330 Atom, 1GB RAM, 160GB HD,
Optical SPDIF. £150 + delivery.
Ignore all the advert descriptions and the R3600/R3610 stuff go by the
manufacturers product code. The suppliers are pretty confused and often
get the description wrong.
Worth searching for the new dual core version {92.NVDYZ.UI0 } , if you
want to use it for anything that uses the processor, and it also comes
with optical out. Testing mine at the weekend I was watching BBC-HD with
95% Idle CPU. Thats what I call CPU offload :-). With the GPU doing all
the work the single core is fine as a myth frontend. The revo has VGA
and HDMI, but no SVIDEO for people with old technolody TVs (like me). I
am again using the VGA-SCART connection to trial, and I could port the
xorg.conf straight over from the 6200 based frontend, and it worked
straight away. So the only thing missing is a remote.
As a few other posters have said, don't mess around, buy one. I was
going the self build route, but buying a Zotak board, a DC-DC power
supply and adaptor, 1Gb RAM a case and a 2.5" HD will cost way more.
best regards,
John
