I will study the logs.

In the meantime, what kind of tuner issue would cause this problem?
It seems highly unlikely that the tuner would suddenly develop a
problem: it's a HDHomeRun, which means I didn't physically touch it
at all.  It's worked without issue for a long time now.  Seems
unlikely that it would develop problems right when I split my
combined FE+BE out to two separate machines.

Is it possible that I mis-configured the HDHomeRun when setting up
the new BE?  What kidn of configuration problem would lead to this?

Also: the videos play just fine, start to finish, as long as we
don't try to search.  So they are being recorded correctly.  And
since they are recorded correctly, I don't understand why
mythcommflag --rebuild doesn't fix the seek table.  Is it possible
there is some other issue at work?

Also: my wife noticed another quirk: some videos that we initially
thought were OK are only OK until you seek forward or backwards a
few time.  Then the seeking functionality starts degrading: first
the amount of seek starts getting random, then seeking forward makes
the video go backward and vice-versa!

Any more help would be greatly appreciated.  WAF is plummeting
rapidly!

Thanks,
Matt
