No.  You'll feed the output of your digital cable box into your MythTV PVR,
and control it via an IR blaster-type device (so Myth can perform channel
changes).  This is because the digital cable feeds are encrypted, so there's
no way to feed them directly into the Myth box.  This also, incidentally,
makes HDTV out of the question.

Incidentally, I'm also on Shaw Cable and have a Motorola DCT-2524.  It works
beautifully with my blaster from irblaster.info and the DCT2500 remote codes
(and quickly, after I removed the delay between clicks in my channel
changing script).

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.

3.) Front End vs. Back End

You could, but then you'd have this big, hot, noisy PC in your living room.
The advantage of a split system is that you can have a big BE with fans and
hard disks whirring in some closet somewhere, while your FE can be small,
quiet, and stylish.  But it really is a matter of preference.

4.) Wireless USB extender (completely off topic - for a MAME system)

Can't help ya here. :)
