I had been running trunk for the past few days, but reverted to 0.20.2-fixes.
(I'm using the same build level of both (14917, IIRC), and the updated schema
appears to mostly work with the older branch.)  My attempts at getting the
channel changer working right, which I thought I had fixed in the previous
message, haven't worked so well...I think it might work for recordings, but
doesn't work so well for live-TV testing (where I get lots of
"RingBuf(/some/path/to/file.mpg) Error: Invalid file descriptor in
'safe_read()'" messages from the backend).

I didn't know there was an internal changer in trunk.  If I switch back to it,
how do I enable the internal changer?  I didn't notice a checkbox for it, but I
might've skipped right by it.
