Yes, the log transcript I sent had ellipses to indicate where I put in
cuts.

I tried deleting the last recording in the log, the one immediately
before it, and the next one in the sniffer output. No go. It still
died at exactly the same number of recordings. It died at the same
point (i.e. after 348 recordings), altough #348 is now a different
recording.

I tried three times. The middle result was 16.09Mbps. The other two
results were 12.x Mbps and 17.77Mbps.

No.

I tried "make host". The host dongle isn't having this problem -- I
can go to "watch recordings" and see a full list. The same code used
to build an MVP dongle has this error. So it seems like the problem
is more about resources and/or the MVP environment rather than an
actual code issue.

I tried a number of versions on the mvpmc, as per earlier emails. No
joy.

Upcoming Recordings -- no, same error ("mythtv backend connection is
not responding")
Live TV -- working.
Schedule Recordings -- no, same error ("mythtv backend connection is
not responding")
Program finder -- allows browsing of show titles. If I actually
select a show to list episodes, same error ("mythtv backend
connection is not responding")
mythtv utilities | previously recorded -- hangs.
mythtv utilities | delete recordings -- hangs.

"All test successful".
