"fetch channels from listings source" didn't work well the first time,
missing quite a few channels.  I just tried it again, with the revised
Schedules Direct lineup.  MythTV still doesn't show program data for 807
= WHDH HD, and it still crashes when I try to watch it.

I then tried a manual recording, which also failed but did not crash
MythTV.  

Here's what I found in /var/log/mythtv/mythbackend.log:

Nov  9 21:30:42 eowyn mythbackend[1404]: I Scheduler scheduler.cpp:2033 (HandleReschedule) Reschedule requested for id 76.

So what is "Unknown tuner type = 0x2000", and 
why does "SetChannelByString(807)" fail?
