Hi I'm new to Media Center and I like it a lot, but I would like to know if
it's possible to disable the "live tv pause buffer" because it's really
making my Hard Drive heat up while recording programs I'm watching but never
told it to record. I don't really need this feature but I can't seem to find
an option to turn it off.. is it in the registry or something?
Thanks in advance.

But there is a way to decrease it if it's eating too much space.
It are indeed registry settings, and someone wrote a script to increase
it, but I suppose it can be used to decrease it too.
http://thegreenbutton.com/forums/1/85967/ShowThread.aspx
I've included the theory and the script downbelow, but I really suggest
you check out the original forum before you use it.
It has(/d) links to Exe versions too.
(I have NOT yet tested them myself, as I find the standard time enough
for now)

Theory
kendawg RE: Increasing the pause buffer
http://thegreenbutton.com/forums/1/85967/ShowThread.aspx
GREAT find, skybert. It seems you are somewhat confused on what the
settings actually mean, so here's some more info on the topic for
everyone... What the DVR/BackingStoreEachFileDurationSeconds does is set
how long each buffer file is, in seconds. So when you set it to 600, that
means each buffer file is 10 minutes. The default is 300, or 5 minutes.
The DVR/BackingStoreMinNumBackingFiles determines the MINIMUM number of
files that will be kept for the buffer. The default value for this is 6
and IT WILL BE RESET TO 6 IF YOU TRY TO CHANGE IT. With the default file
time of 5 minutes, you get a 30-minute buffer (5x6=30). But with your
settings of 10 minutes per file (600 seconds) and a minimum of 6 files,
we now have a 1-hour buffer. 10 minutes/file x 6 files = 1 hour.
The DVR/BackingStoreMaxNumBackingFiles is the MAXIMUM number of files
that will be kept for the buffer. I don't think this matters much, but I
have mine set at the default of 8 files. That way, with 10 minutes per
file, I have a max buffer time of 80 minutes. You CAN change this value,
but Im not sure what it will actually do.
And, like skybert said, for anyone who wants to try this, you can't edit
these keys directly or they will get over-written with the default
values. You have to make these in the "HKEY_LOCAL_MACHINE\SOFTWARE
\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners" area
alongside the RecInfoVersion:
BackingFileCountHigh
BackingFileCountLow
BackingFileDuration
-----------------------------
here are my values, to get a 1-hour minimum and 80-minute maximum buffer:
BackingFileCountHigh 8
BackingFileCountLow 6
BackingFileDuration 600
----------------------------
say you want a 1.5-hour minimum buffer:
BackingFileCountHigh 8
BackingFileCountLow 6
BackingFileDuration 900
...you get the idea...
----------------------------
By the way, this does eat up a lot of hard drive space. I just checked
and ONE of these 10-minute files takes up 762MB. It's probably not always
exactly that, depending on the show, but close. At that rate, a 1-hour
buffer will eat 4.5 gigs...but I guess it doesn't matter because they are
always being deleted as new ones are made.
anyways, thanks again skybert

It should be a DWORD.
You could also simply copy the following into a file a name it 1-
hour.reg, then double click the file to get a 1 hour buffer:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media
Center\Service\Video\Tuners]
"BackingFileDuration"=dword:00000258

Please log in for more thread options It can not be turned off.
However since you never use the time shift or record capabilities then I
suggest you use the TV application software that is available for your tuner
since you can watch Live TV with it without enabling time shift and you will
also get better Picture Quality since the program is not being compressed
and encoded before being received by Media Center if you do not have time
shift enabled.

If simply using your hard drive is making it heat up as you claim then you
have other and far more severe problems to think about. Reading / writing /
seeking 24X7 is the norm for a drive and if it is installed and cooled
properly the temperature will not vary noticeably -- or at least not enough
to matter in the real world.
