Since you have proven its not the tuner itself, it could be an IO issue or
a playback profile issue.

Unlike streaming it from hdhomerun_config Mythtv records everything to
disk, even live tv.  Perhaps your disk is severely fragmented, you have
some other process consuming IO, etc.

If everything looks good from a disk perspective, you might play around
with your playback profiles... disable any deinterlacing, enable/disable
vdpau, etc.
