The "important detail" you might be missing is the fact that the HDHR  
can't receive analog transmissions, only ATSC and unencrypted QAM.

Not that it isn't a great device IMHO, but I think your original post  
mentioned analog.

Some cards (like the HD-3000) can receive digital and analog signals,  
though their performance as analog receivers is limited to that of a  
simple frame-grabber which means that your CPU will have to do the  
encoding. This may or may not be a problem for you.

Personally I'd use a hardware-encoding card for analog like the PVRs.

Although you can get a single card to do both jobs it's like anything  
else in life: use the right tool for the right job, or you may not be  
happy with the result.
