Yup. I think the only major functional difference between the two is that the 
HD-2000 is a bttv card in NTSC mode, the HD-3000 is a cx88 card in NTSC mode. 
I had no problems viewing NTSC material w/my HD-2000 (outside Myth).

That would definitely be nifty... Or if that isn't entirely feasible, maybe a 
PVR-500 with one input for HD, one for SD... You can always hope!
