Sad to report.  Changes did not solve the stuttering problem.   
However, I got rid of the "ivtv warning: i2c client addr: " messages  
by removing the "alias msp3400 msp3400-ivtv" from my modprobe.conf  
file.  Now it uses the ivtv version instead of the kernel version.  I  
guess there was a conflict with that module as well.

Perhaps this helps point to the cause:
   -When I use mplayer to play /dev/dvb/adapter0/dvr0 with ATSC data  
The Picture looks great and plays fine, however the audio is slightly  
out of sync.

   -When I use xine to play the save device stream the video works  
but has trouble buffering (eventually dies) and I get no audio.

   -Within myth the HD audio/video go into a play-pause cycle.   
Different timings based on the settings, but it never goes away.

I'm wondering if it could have something to do with the ring buffer?   
I only see this issue with the HD information from the HD5000 card.   
The SD programming plays just fine.  I've bumped up the "HD Buffer"  
in the front end set-up but that didn't seem to help.  Is there a  
magic number I need to use?  Or something a missed perhaps in setting  
up the card?
