Video card required for WHS install?

[buymysoul]

I've been trying to set up SageTV on my Windows Home Server (WHS) and keep running into little roadblocks when recording TV.

At first I hadn't realized that I needed to have Directx 9 and Java installed...actually, I'm still not sure if those are actually required with a WHS install or not (I've seen some posts that imply otherwise) but I uninstalled SageTV, installed Directx 9 and Java and installed SageTV again. I can configure everything just fine but when I record a show it goes away after it is done recording. If I actually try to tune in a channel over remote desktop, I get a "no Signal" message. I did do a trial run with sage on a Vista box in the house and that worked fine.

I'm using an HDhomerun for QAM content but it dawned on me that maybe Sage still wants a video card to record? I feel pretty silly for not thinking of this ealier, I was just thinking about a pure digital stream from the HDHR, through Sage to my hard drive but maybe some video hardware is still needed?

Searching through the forums, I've seen lots of requests for a hardware list when someone asks for help so don't think this is just gratuitous:

WHS PP2
AMD Turion 2.0Ghz
2GB RAM
Drive Outside Pool formatted with 64k clusters
HD Home Run tuner

Thanks for the help,
