I have a tv that needs the hd tuner to get hd programming. I got the motorola dvr from Comcast...does this also work as an hd tuner? I mean, can I plug in an antenna to the box and receive local channels in hi def?

It's bothering me, because although I get a great picture and hi-def channels, I've no way of really knowing if it's a true hi-def picture.

If anyone can help, I'd appreciate it.
