Replace capture device with MPEG encoder.  See PVR-USB2 or HVR-1900.

Run ethernet anyway.  The wireless spectrum is only going to get more 
crowded, and as eventually progress up from standard definition through 
HD DVB-T to Bluray, and add additional frontends, you rapidly run out of 
headroom.

TVTime really doesn't do much of anything with your tuner.  The video 
frames are copied out of the tuner capture buffer, and into the graphics 
display buffer, with little to no manipulation.  Audio is left up to the 
system to pass through to the speakers.  When you are instead trying to 
capture and compress, MythTV is necessarily much more complicated.  The 
entire reason everyone recommends MPEG encoders for analog capture is to 
completely bypass this complication.
