I'm running 3.9.316~g238636f~precise.
TBS-6985 quad DVB-S2 + Hauppauge HVR-1100 DVB-T or something similar.

Now, it seems like epggrabber just runs quite often. And when it does, it interrupts streaming for a while.
Every time epggrab appears in the log, the picture stops for about 10-15 seconds. And that is very annoying.

Is there any way to disable epggrab on adapapters that are subscribed to service? Or maybe somehow change weight so that streaming has higher priority?
It could be that weight 1 already means the lowest weight (or is it the highest? not sure) but still it takes over (well, it's the same mux, but something still happens) adapter6 that is subscribed to a service, as can bee seen in the log.
All my four inputs have the same config (4x1 diseqc connected to 1w, 5e, 13e, 19e). So acutally epggrab could be bit more intelligent and if all adapters have the same networks then epggrab could do it's thing on only one adapter, no need to subscribe to all of them.

Of course it could be something else too and it's just coincidence that epggrab shows up just the same time.

I'm now experimenting with full mux rx, I can report back later if it changes anything.

An example log output when the problem happened:
