The pause could be a very short one (less than a second) or longer, it will be sufficient to make it flow normally again. This happens on the combined BE/FE and on the remote FE. I don't see anything in the logs and it always works OK when watching recordings.

Daniel,

This has been an issue for me for quite some time.  I originally posted the issue in December 2009 in the following thread: <http://www.gossamer-threads.com/lists/mythtv/users/414307>.  As you can see, it only got a few responses even though our setups seem to be fairly standard mythtv installs.  Since then, I've kept my system updated with the latest 0.23 fixes and kept the hdhomerun updated with the latest firmware, but I have not found a solution (or anyone else interested in finding one).  I think the problem is probably a lot more common than the posts would suggest, but perhaps it hasn't gotten much developer attention since it only involves live TV, which the developers detest.  If anyone else has the same issue, or better yet has a solution, please reply to this thread and maybe we can at least try and piece together what is going on.

Nick
