So... to see if I have this right... I would run the physical cable line 
in to the Cox DVR/tuner as I am now... then split the output... output A 
would go straight to the TV... say as Input 1 on the TV. Output B (of 
the split) would go to the input of the Myth box and the Myth box's 
output would then go out to the TV... say as Input 2. So from my TV's 
perspective, Input 1 is the Cox box and Input 2 is the Myth box, but the 
Myth box is seeing everything out from the Cox box and allowing me to 
record it all... so basically, I only use the Input 1/Cox tuner/Cox 
remote as the tuner (to get all my channels) and for ordering 
OnDemand/PPVs, but I use the Myth box as my DVR, DVD player, PC (web 
browsing), etc. Sound about right?

I have another TV in the master bedroom that is just a regular (ie: 
non-wide) TV and a Cox tuner/DVR... basically there's no DVD connected 
and its not the primary/shared TV... so I'm thinking I'll get everything 
built and working upstairs first and if all is to my liking, then move 
it downstairs.

Question on splitting things... obviously I need to split after the Cox 
box to get channels over 99. However, while I have true coax cable going 
into the Cox box, I'm running composite or s-video (I don't recall right 
now) out to the TV. Will I lose any signal quality or audio/video 
quality if I come out from the Cox box via coax and split the coax back 
to the TV and Myth box? I'm just thinking that splitting the coax 
connection is a lot cheaper than splitting an 
s-video/component/composite connection.
