Have you considered using an external USB or Firewire device to do some 
of the capturing?  Plextor makes a line of external tuners that work 
well with MythTV.  Some of Hauppauge USB stuff also works, the HVR-950 
provide ATSC and analog support however I don't think that analog is 
working with MythTV right now.
