#3495: Can't view a valid QAM channel unless tuning to the other channel on the
same freq first

I am using QAM and have two channels on the same freq. (multiplex) Here
is their channel.conf values.
KVUE1:573000000:QAM_256:64:65:42
KEYE1:573000000:QAM_256:66:67:41
When watching live TV I can not view KEYE1 with out first tuning to KVUE1.
If I don't this results in a black screen and mythtv telling me it can't
get a signal. If I then switch to another channel say like...
KXAN1:585000000:QAM_256:67:68:2
and then try to go back to KEYE1 I get the blank screen again unless I
again go to KVUE1 right before.
If I have recording on KEYE1 it just puts an empty file on my recordings
screen.
I did notice in the backend logs that I get a "DTVSM(0): Ignoring
encrypted program" when the problem occurs but that doesn't show up if i
go to KVUE1 first.
The problem is with mythtv because I used azap to tune to KEYE1 and was
able to view it with mplayer without going to KVUE1 first.
I am using gentoo and the mythtv-0.20.1_p13344 ebuild and through trial
and error figured out the bug entered mythtv sometime after mythtv 0.20
because the ebuild 0.20_p13110 worked.
I know the devs don't like the ebuild version numbers so here are actual
version info.
The version that works correctly:
mythbackend ~ # mythbackend --version
Library API version: 0.20.20060828-3
Source code version: exported
Options compiled in:
linux release using_v4l using_oss using_alsa using_ivtv using_lirc
using_dvb using_x11 using_xv using_xrandr using_opengl_vsync using_opengl
using_frontend using_backend using_bindings_perl
The version that is broken:
mythbackend ~ # mythbackend --version
Library API version: 0.20.20060828-4
Source code version: exported
Options compiled in:
linux debug using_v4l using_oss using_alsa using_ivtv using_lirc
using_dvb using_x11 using_xv using_xrandr using_opengl_vsync using_opengl
using_frontend using_backend using_bindings_perl
The card I am using is a AirStar-HD5000-PCI

Attached to this ticket is a gdb and mythbackend log of the problem
happening. I first went to KEYE1 (1531) to show I can't view it. I then
go to KVUE1 (1511) and then back to KEYE1 (1531) to show I am able to view
it this time.
