Yes, It's a bug in the ATI drivers. There's a hack that you could use
to get rid of the problem. It didn't work for me, though..<br>
Here's a quote from the MythTV-talk forums: <br>
---<br>
<span class="postbody">You need to recompile with
USE_ATI_PROPRIETARY_DRIVER_XVIDEO_HACK enabled
<br>
See: <a
href="http://svn.mythtv.org/trac/browser/branches/release-0-20-fixes/mythtv/libs/libmythtv/videoout_xv.cpp#L67"
rel="nofollow" target="_blank">http://svn.mythtv.org/trac/browser/branches/release-0-20-fixes/mythtv/libs/libmythtv/videoout_xv.cpp#L67</a>
<br>
Also you may need to modify this function to include your Xv adaptor: <a
href="http://svn.mythtv.org/trac/browser/branches/release-0-20-fixes/mythtv/libs/libmythtv/videoout_xv.cpp#L3448"

</span>---<br>

I don't think this will be fixed in MythTv so the only option is to bug
ATI to fix their drivers. I'm personally probably going to just <br>
get rid of my ATI card and try NVidia. <br>
