mysql -u mythtv -pmythtv mythconverg
select chanid, title from recorded;
The first digit of the chanid is the device that did the recording. Or,
you could do this:
select * from channel where chanid = 1234;
once you know what chanid your show was on and you can match the
sourceid with what's in the cardid table. "describe <tablename>" is
good for finding out what info is available.
It should be easy enough to test the two-recodings-simultaneously
theory by creating two telnet/ssh sessions and having one cat the 350's
output directly to its playback device (cat /dev/video1 > /dev/video16)
and then doing a cat on the 250's device to a file or /dev/null.
Actually /dev/null would test if you're able to do file i/o on both
devices simultaneously, if the 350 output is in sync with the 250 going
to /dev/null and not with it going to a file then i/o performance is a
likely culprit. I guess there are lots of possibilities but that's
where I'd start, at the raw device level.
