Every now and again, whatever it is I'm watching flicks to another channel. Then as you cycle through the channels in myth (in an attempt to get back to what you were watching), it quickly becomes apparent that only channels from one multiplex are available - it's like the channels from other multiplexes were never even there. It's not always the same multiplex when it happens.
I have no idea whether this is related, but when I look at the backend status, it shows 40 encoders! I only have two dual tuners, so 4 tuners in total (nova-T-500s). Furthermore, when I first installed, and this happened in 810 as well, the card was detected 17 or 18 times (i just added the first 4, and then ignored the rest). Again, no idea if this is related, never caused a problem before.
Any ideas? I read that doing a "delete all" on the video sources solves the "many encoders" issue, but it hasn't worked for me.
