Whether or not to shut it down is completely the decision of the user.
 But for example there might be some guys worried about running their
laptop battery down so they prefer to shut it down.  Or some guy who
is really concerned with his power usage in general and wants
everything off if he isn't using it.

However, in my case since VDR is my main tv/media source, it would be
annoying to have to boot the computer every time someone wanted to
watch/listen to something, therefore the box stays on 24/7.  Thus,
never having use for shutting down.

Read speeds should be at least acceptable on a modern device, but
writing can still be quite slow.

The easiest starting point would be Debian Live
 because it's designed to be
customisable (so you can easily pre-install VDR etc, and hopefully
easily get it to automount other filesystems eg NFS) and to search for
another partition with a specific label on the stick to use as a
writable home partition or even a writable root.

Google returned some results from this query: how to make a live usb
run from ram

http://www.pendrivelinux.com/ubuntu-toram-how-to-make-ubuntu-boot-to-ram/

This is an idea, but with Linux there is no limits :)

Good luck.

Sorry, I do not get your reasoning. Do you mean if a system uses less
than 5 – or a different number – watts it does not need to be shut down?

What you could do is to make a boot process similar to most rescue or
live-cd/usb. The idea is to make the whole thing run in ram, so boot
by using network or memory stick, copy squashfs to ram and run from
there. Should be lightning fast.

Good idea.
I suppose this one 
http://geizhals.at/deutschland/a439283.html
should be sufficient.
I wonder if that's going to be faster (no seek times)
or slower than my hard disk.

The only remaining advantage of an nfsroot system
being that I can turn the power off without needing
to shut the system down.

I've been using usb stick for both VDR and my fileserver.  Works just fine.

Another idea: if there's a spare USB (2.0 High Speed) port you could use
a memory stick instead of NFS.

Indeed, the only two applications running on desktop side would be X
and the application which is your frontend, either xine or
xineliboutput.

xineliboutput does have the advantage that it has a media menu
built-in for alternative media. It can do things like watch
dvd/iso/pictures/music/blu-ray/avi/wmv. The latest snapshot supports
cropping when xineliboutput was set to use video vdpau. And you
already have a nvidia machine.

The desktop doesn't play DVDs or BlueRays. This is done by
xineliboutput, xine and xbmc ... To start xbmc a lircrc
skript for irexec would be enough. No need for a desktop.

Running VDR is important, but not the only purpose.
Surfing the internet, watching DVDs and BlueRays, etc.
is a lot of fun on an HD beamer. :-)

Currently, the airflow is provided by the power supply fan only.

I agree. 
As I said, A silent 4x4cm fan seems to be hard to find.
There are very nice silent 12x12cm fans,

That will not fit. The power supply sits above the board.

Re: [vdr] Record HD broadcasts not working if the FF card is the primary device

Hi,

Recording from a non-primary device, thats what I do: As ARTE-HD is
DVB-S2 and my FF supports DVB-S only I use the DVB-S2 card for
recording, of course.


I'm sure that switching to an SD channel during the recording will
work fine. On the other hand side, I normally don't sit next to my VDR
during recordings and make sure that they work.
