I'm running directv2pc on an HPs3020n.When I do dtv2pc playback scan it shows red button which says I need to upgrade the NVIDIA GeForce 6150 LE.Which card will work on this mini comp.It won't take a standard size card.
I personally just picked up an ATI 4350 for use in what will be my HTPC. This is a 1/2 height hard that I will be mounting in my HP dc7700 small form factor. You could also give this a try.
