The /dev/vbi stuff work mostly, but if I set filters in a loop, two at a
time as you suggest, with at least 1 second pauses between checks, after
30 or so iterations, the filters won't report any more data, even though I
know there's data there, and it will show up if I start the scan closer to
the PID with know data. I've tried it with calling VIDIOCSSHUTDOWNFILTER
on each pass, and without, and it doesn't seem to change. Any suggestions?

Also, during the scan, it's possible for the kernel to start reporting
"outcommand error", and the only way to get rid of it is to remove the
modules and reload them.
