I have serious doubts about the value w/o timeshifting.

It's strange also for me (it happens only on Android).
Will retry again.

You can find a good explanation about how MPEG GOP works in noggins post.
I guess your DVB-T device takes longer to warm up than your DVB-S device. On channel switch dvbviewer just sends a channel switch command whereas xbmc/PVR completely terminates the connection and the DVB device will shutdown just to start up a few milliseconds later.

I'm not such an expert and don't want to disagree with you, but Mediaportal plugin takes always 2-3 zapping time, on both dvb-t and dvb-s. Only Dvbviewer xbmc plugin has such differences.

I don't need and want any logs regarding switching times. But you can go ahead and play with the code. Nobody will stop you.

It would be wonderful, but I'm not a programmer and don't have such skills. Only trying to help the development testing on real hardware.
Anyway, thank you for your efforts
