Can I record in HD from the coax TV Out of my set top box?
kendire12b asked:
Clear QAM and OTA HD use coaxial cable (and are HD), but I’ve been told the coaxial TV Out on an HD set top box would not output in HD. I have a PCI HD tv tuner card that supports clear QAM and ATSC. Is it true that connecting the coax TV Out from the STB to the tuner card would not result in HD recordings? If so, is there a component-to-coax cable that will allow me to record in HD? It would be nice to record cable HD channels w/o renting the company’s DVR.

The only PC equipment available to record cable in HD (forgetting whatever may be available on QAM) are cable card PCs. There are very few of these around right now. The QAM can be recorded by using your QAM card and connecting the cable directly to your tuner (not through the box). You’ll get whatever your cable supplier furnishes in the clear.
No, because set-top boxes don’t output in HD on the coax output. To do so would raise the cost of the box, and would allow for “unsecure” digital signals to be captured and recorded (and then copied and shared), which is something the content providers are doing everything to prevent.
