Sounds like a signal quality issue.  What does the picture look like if 
you hook a TV to the signal input you have going into your MythTV box?  
What does another progam give you for quality inside your box like xawtv 
or tvtime?  Poor splitters and cable segments are notorious sources of 
signal problems.  Try putting the cable directly into your MythTV box 
and see if the signal improves.  If it does, your splitter or cable 
segment after the splitter is a problem.
