This is probably a reception problem for which there are many helpful
discussions on the user's mailing list, cable installers often forget
to ground the cable properly and people often use RG-59 cables when
they need to use RG-6.
With the HDHomeRun it could also be a networking problem. In which
case you need to google for any known problems with your network
drivers or with the switches or hubs located between your computer
and the HDHomeRun. Using a preemptive kernel and oversizing your
networking buffers can help.
At this point it looks like this is a use question without any impact
on MythTV development so just CC me on your first e-mail to the users
list about this and I'll follow the discussion there.
