Why no HDTV?  Shaw has a HD tuner available.  So you are saying MythTV
can't record HD content?

> 2.) Dual tuners
>> Can I have two tuners and record 2 shows at the same time?
> Yes, but you'll need two cable boxes and two IR blasters to do it.

My first thought would be to have a second analog tuner as Shaw gives you
full Analog cable when you get Digital.

So the front end box sits next to your TV and you stream the recorded
content from the backend? I am bit confused as to where each component
(tuner cards, TV out cards, disks etc are placed).
