I've been looking at the same problem on another thread.

What version of IVTV and MythTv are you using. I didn't have the problem
yesterday but then I upgraded to MythTv cvs and Ivtv 0.19.

If you look at the output of mythfrontend you will see an error 
something like this when you switch
to live tv:
* Couldn't find Xv support, falling back to non-Xv mode.
* MythTv performance will be much slower since color
* conversion and scaling will be done in software.
* Consider upgrading your video card or X server if
* you would like better performace.

If I run xvinfo I get
X-Video Extensions 2.2
Screen #0
: no adapters present

That should list a load of information about the cards present.

So I think it looks like its an IVTV problem
