[mythtv-users] segfault scanning ATSC channels

[Yan Seiner]

I recently upgraded to 0.20.2.

All appeared well, except that new recordings didn't work.

So finally today I got a chance to try to fix that.  I deleted all 
tuners, and set up new tuners.

The analog stuff appears to work OK, but I get a consistent segfault on 
ATSC channel scan.

Specifically, as soon as it gets done with Channel 17, it segfaults.

Here's the last few lines of screen output from mythtv-setup:

And here's dmesg.  The only thing that seems weird is the "or51132: 
unknown status 0x00" stuff.  Anyone know what that's about?

Linux stuff has made big progress over the competition. When things sit and don't start right away, we have a watch, and those poor guys have to settle for an hourglass.
