Yes.  The mpeg recordings are all HDHomerun, and the H264 720p60 is from the
HDPVR.  It's set to whatever the default is - I've never changed it.  I'll
try changing the bitrate and see what happens.  I do observe though that the
CPU hovers in the low 30 percent range when playing back.  So I don't
understand the reason for the pauses, if it's caused by too high a bitrate.
