Zap buffer delay
#1
Zapping between channels always takes >4s. Modified some network and pvr
settings in advancedsettings.xml without results. Can buffer/cache be
tuned outside of source?

unfortunately, zapping itself is relatively slow on enigma supporting hardware (something to do with the driver structure for the tuners).
I've had a couple of modern e2 boxes (gigablue, Vu+, Dream and Xtrend) and all were substantially slower at zapping than my old Nokia dBox2 with Neutrino, so the limitation of it is kind obvious.

that said, i've seen software that retrieves EPG and zaps/streams via the WebInterface (Blackbox on iOS in this case) zap quite faster than XBMC/Kodi ever did ... so _some_ improvment should definitely be possible ... hopefully you can find something about that, as I believe the Vu+ plugin for Kodi is close to "finished" if only it wasn't for the sort of static/slow EPG and zapping performance ...

Sharing your tuners with vtuner on the box together with tvheadend gives faster zapping.
As bonus you have working subtitles on channels with Teletext.

Dear Leatherface,

I would appreciate if you kindly elaborate on this. I have Vu+ Duo2 and Kodi Helix Openelec installed on NUC. At the moment I use Vu+/enigma add-on on Kodi. It is working OK. But I read on several forum posts that tvheadend works much better as backend server. But I have no idea how can I make Vu+ Duo2 and tvheadend working together? Where will vtuner and tvheadend server be installed? on Vu+? on Kodi? or on a separate box? And how?

Thanks in advance.

@refx: I think you used the incorrect buffer settings in the advanced.xml. Please check out this post:
