After spending many hours playing with Vista every time the same problem
comes up.

After a fresh install the pc goes into sleep mode and after installing
several software and plug-ins it still does but after opening MCE for the
first time and going through all the settings the pc doesn't go into sleep
mode anymore and after testing why I found out the problem is the Media
Center Receiver Service (ehrecvr). As long as this service is in the windows
task list the pc stays awake. When deleting the ehrecvr from the task list it
returns after a while so this won't help. Service will be started manually
(standard vista setting) so why does it start automatically when deleting it
from the task list. The only way to stop this service is by disabling it.

I figured out this problem only appears when recording to WHS (Windows Home
Server) the way Ian Dixon and Richard Miller mentioned here.
http://iandixon.co.uk/cs/forums/thread/2608.aspx.

Recording the same way with MCE2005 to WHS works perfect and the pc goes to
standby.

When recording to a local disk with Vista there is no sleep problem

My power options are set in high performance and I want my PC in sleep mode
after 10 minutes inactivity.

So I wonder if this is a Vista bug or am I doing something wrong. If this is
a bug I hope this will be solved soon.

Thanks,

Problem update.

I just found the reason why sleep mode won’t work. It has to do with the
TempRec folder wich will be automaticly placed in the recorded tv folder. I
tried to change the the location in the registry but after restarting the
“bad” service (ehrecvr) the TempRec folder is right where it was.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media
Center\Service\Video\Tuners\DVR\IO\Writer]
"DVRDirectory"="\Home-server\TV-Opnamen\TempRec\
"FirstTemporaryBackingFileName"=""
"DeleteRingBufferFiles"=dword:00000001
"RingBufferFileName"=""

The problem will be solved when this TempRec folder can be replaced to
another location like F:\TempRec

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media
Center\Service\Video\Tuners\DVR\IO\Writer]
"DVRDirectory"=" F:\TempRec \
"FirstTemporaryBackingFileName"=""
"DeleteRingBufferFiles"=dword:00000001
"RingBufferFileName"=""

In MCE2005 I could easly change the location of this tempRec folder so I
don’t understand why this isn’t possible in Vista anymore?

Taking a look in the computer management of the Home-Server (open files)
this is what the log says while Vista is recording.

G:\TV-Opnamen\TempRec\TempSBE\SBE93F7.tmp        ALEX        Windows        0        Write

When stopping the recording and refreshing the open files list the log says:

Open File        Accessed By        Type        # Locks        Open Mode
G:\TV-Opnamen\TempRec\.TmpSBE        ALEX        Windows        0        Write+Read
G:\TV-Opnamen\TempRec\TempSBE\MSDVRMM_4039540896_6553600_54        ALEX        Windows        0        Write+Read

G:\TV-Opnamen\TempRec\TempSBE\SBE9224.tmp        ALEX        Windows        0        Write

This means that Vista still writes data to the TempRec folder even when
there is no recording or MCE window open.

Find me a way to change the location and the problem is solved I guess.
