Have you gone through the setup menus?  Everything you can imagine including 
vsync and deinterlacing are in the setup menus.  I would highly recommend 
spending some time in the setup menus to familiarize yourself.  MythTV is 
highly customizable.

As for your picture quality problem, I think myth defaults to 480x480 and a 
fairly low bitrate.  Change the resolution to 720x480 and turn up the 
bitrate for a better picture.  Again these are in the setup menus 
(specifically recording profiles).
