(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 Here is the modinfo on b2c2_flexcop filename: /lib/modules/2.6.19-gentoo-r5/kernel/drivers/media/dvb/b2c2/b2c2-flexcop.ko author: Patrick Boettcher
