The cable card concept is further crippled by only being avalible to OEMs... I can't build a HTPC with cable cards so it's worthless to me.
I'm surprised you haven't comment in the HTPC thread, my last post was a screen shot of my system recording 5 shows at once, three SD from my three PVR-150s and two in HD from my HDHomeRun (QAM). Very cool stuff.
