Huh... that's funny... the cable show notes about the motorola tuning resolver linked to the post I listed... at the time I posted that story had an additional line that said it would work with any cablecard device.

I think someone went back and did a little editing.

I know it said it cause I read the thing 3 times just to make sure I wasn't seeing things.

No, the TA will not work with any CableCARD tuner. It doesn't say that in that story (which is a month old BTW).

Chris, you may want to check out the following story...

According to motorola this SDV tuning adapter will work with any cablecard tuner.

I hear what you're saying Chris, but since the DCT is basically just a USB network device as far as Windows is concerned, there is a good chance the TA will be the same, and if so, then the DCT and TA can communicate over IP via the PC.

The diagram doesn't apply because it is for UPCPs which there are no external version of.

Ben, your thinking backwards. Everything you said above is kind-of opposite how TAs work. Take another look at the block diagram and then remember that the USB connection in the block is from the TA (which has one USB) to the UDCP (which has one USB). This leaves no USB connector from OCUR to PC.

I'll shoot you an e-mail with a bit more, but going from TA to PC does nothing at all. Without going through the CableCARD, you can't tune anything. Windows doesn't communicate with the TA, the OCUR would.

I'm sorry Chris, but I'm totally not with you on this one. Although I agree it is entirely possible that the Tuning Adapter will never work with VMC, your USB reasoning is not plausible.

All they have to do is plug the USB cable from the TA into the PC. Why would the TA need to go through the CableCARD? All that needs to happen is Windows needs to request the frequency from the TA and then instruct the DCT to tune that channel.

I supposed the TA needs some sort of security identifier to be permitted to communicate on the network, but I'm not sure if the FCC mandates it be separate like a normal STB. And if it does, then I'm not sure why it couldn't communicate with the DCT via the PC.

Either way, only time will tell.
