Playback error with headless setup

[zorak]

Hi all - I've scoured the forums and googled on everything i could think of looking for an answer to my problem without any luck.

I setup SageTV with a Hauppauge PVR350 running on Win XP Pro SP2 without any glitches (until now).

After everything was setup properly and working fine, I decided to remove the keyboard, mouse, and monitor, and move the box closer to the tv (I really don't need all of those things attached to the box since I can control the PC using the Remote Desktop Connection feature in XP from my laptop if I need to make any changes.)

The problem is that with the monitor, keyboard and mouse removed, I get this playback error in Sage:

There was a Playback Error in playback. Details:
sage.PlaybackException: ERROR (-4,0x80040217): There was a
problem rendering the video portion of the content for
playback.

Ok, so I tried just reattaching the monitor - still got the same error. So I tried adding the keyboard - still got the same error. The only way I've found to make the error go away is to reconnect all three devices.

I know there must be a simple solution to this - but I can't figure it out - so hopefully one of you can help

Here's my setup:
Pentium Celeron 2.5ghz
Onboard video (Intel 82845G updated driver)
768 meg RAM
2 60 gb hard drives
Hauppauge PVR350 (1.18.21.22301)
SageTV 2.2
DirectX 9.0
Norton Ghost
Norton AV (not running)
