HTPC the build begins
Really the buying begins the case is on its way an Aplus GL3
and I am down to two motherboard chipsets 780G or 785G
depending on the processor- it looks like an athlon II x2 250
is the best bet with its low power requirement I did fancy
going x3 but keeping the price down to around £60 I don't
see a low power option so if anybody has an idea I'd be
interested to hear it.

I do not think you can get ULV CPUs for desktops yet although they must
probably will surface at some point (for low voltage desktop machines) my
PDC 1.3ghz ulv is 90.5% as fast as a Core 2 Duo 1.66ghz (going by wei
scores) yet the machine its in gives 6.5 hours web usage... thats pretty
impressive although it does have a 6 cell battery which helps. My old EEE PC
901 Atom 1.6ghz gave 4.5 hours web usage and it also had a 6 cell battery so
either the 6 cell in the EEE is much less powerfull or the machine with ulv
cpu is doing a fine job at doing exactly what it was designed for...

I'm pretty well limited to AMD I need the 780/785 chipset for its onboard
video's ability to decode bluray in hardware for an HD TV output (1080i)
and later for DVB-S2 or possibly DVB-T2 as HD terrestrial comes on line in
December ideally to use a twin tuner for PVR applictions i.e. record one
channel while watching another so a decent margin of processing power is a
must of course I can always upgrade later if needs be.

My HTPC has a Gigabyte G41 board with an e5200 overclocked to 3.3ghz, 4GB
Crucial RAM, Sony Blu-Ray, 1TB HDD, 9800GT Low Profile, Antec Minuet 350
mATX case, Hauppuage HVR 2200 atv/dtv dual tuner, Windows 7 HP its great.

Sounds the ticket Nick my choice of case is just down to matching aesthetics
with my Sherwood Newcastle Reciever I have a DVB-T in my desktop (Videomate
SAA7020) but I'll wait a bit before diving into the DVB-T2 market at least
until there is a bit more choice or possibly just go direct to DVB-S2 plenty
of time to play with the options.

NVidia 8x00 and better chipsets can decode H264 (BluRay etc) too, but
you need a certain spec to be able to run the advanced deinterlacing
options with 1080i. I don't know how that compares with ATI.
If the video chip can do all the decoding you don't need a lot of
processing power, but it might come in useful if player applications
make it possible to decode 1080i in hardware while deinterlacing it in
software.

The ability of the Radeon HD 3200 onboard video
http://media.bestofmicro.com/4/3/84387/original/chart_hdtv_cpu_load.png
was the decider it really takes enough load off the cpu to allow for other
processes to have headroom. I believe my choice of processor should be
enough ( as its a good deal faster than the those in the test) well at least
until I start seriously looking at satellite options though its difficult to
find comparison benchmarks for most of my intended applications what ever
happens its going to be a learning experience - I'm even going to try
running a linux OS for comparison.

I don't think there are viable Linux drivers for ATI HD video decoding
yet, but support is supposed to be coming eventually. Then you'll need
applications to support its API, unless there's a VDPAU backend. VDPAU
is NVidia's video decoding API which can theoretically support other
hardware too. It is supported by some video players already, but
it usually involves downloading svn snapshots etc and compiling them
yourself, and I think it can still be a bit flaky in some cases.

I have found an Antec "Micro Fusion Remote 350 - UK" case. Is that the
same?
I assume that you are using Media Center in W7 HP (?) - I have found that
is quite good at driving my Hauppauge Nova DVB-S2 PCI card.
I have been unable to download the manual. How is the LCD display connected
and can Media Center display the channel name?

No its better, do not get the Minuet case if planning on adding a 9800gt low
profile the PSU is not up to the job, I only found that out afterwards still
have not put in place a fix.

Yes W7 media center.

Would not know about that sorry.
