I was wondering if anyone has come across an adapter that will convert either a Component or HDMI connector to a coax one? Since none of the current DTV DVR's have a coax out I' thought maybe could use some sort of adapter to convert one of the outputs so its carried thru a coax cable to my TV card

Better just to get a $25 RF converter. It takes RCA composite and turns out coax. Since it is SD anyway there really is no need to down covert from HDMI.
SD DVRs do have them though.

Mertzen is right. Any NTSC/RF Modulator that you'd get at Radio Shack ought to do the trick.

"composite" or "component"?
Composite should go "straight to" your TV card, as mine [two] all have composite/S-video inputs.
If your's doesn't, "got a VCR" as they have coax output with composite inputs.
"Component" is another story, and if you're trying to send it to an ASTC tuner card, good luck.

My bad, I meant a component

I have used one of these Philips RF modulators from WalMart and it works fine with an analog TV.

Im not really sure. I just thought maybe a component plus audio adapter would work so I could send the signal to my computers TV card since it can see HD via a cable company's Coax line.

"The problem is" you would need a ATSC modulator and encoder to take the video and encoded it into MPEG-2, then modulate it into ATSC digital. Not cheap

You may have a Quam/ATSC issue. ATI makes a card with ATSC tuners.

Sorry VOS, I didn't mean to step on you. Your just "faster on the draw" than I am.

"right" that is the "decoder", but you need the "encoder" [see my earlier post].

Unless its OTA, you're not going to get HD on your cpu via coax.
