Same client same TvHeadend server version that I'm using, but I have the TvHeadend server separate from the C2.

I will repeat again, you are NOT going to get rid of the PVR buffering with TvHeadend the very first time it starts, and at random times thereafter, particularly with 720 and 1080i streams using Kodi Jarvis.
This is a known AMLogic bypass rendering issue with both OpenELEC and LibreELEC for as long as I've used both OS's. It may get fixed with Kodi Krypton on AML.

Make sure you have the TvHeadend Addon client configured for predicative tuning. That may help with quicker channel switching. mpeg2 480i/576i channels should be configured for Software decoding (In Kodi > Video > Acceleration) if you want quicker startup.

Sorry guys I cannot help with the Audio problems. mpeg2 + AC3 passthrough Audio works for me properly with TvHeadend Client running on LE from an eMMC. I'm not doing anything special.

See the previous post as well about Static vs DHCP IP router configurations. Experiment with that, it may help some people.

Thanks for getting back to me, I really appreciate it. I applaud your extreme kindness and dedication towards helping the enduser. Keep up the great work man.

I use a separate C2 running Tvheadend 4.1-2130 and can confirm the PVR buffering on the client C2's at first time play and randomly there after. I have tested various levels for cachemembuffersize, readbufferfactor, minvideocachelevel, and minaudiocachelevel.

I pulled HK's version 1.8 kernel and applied these hephooey's (which he got from later amlogic kernel) patches(http://forum.odroid.com/viewtopic.php?f=141&t=21875).

They appear to have marginally increased channel switching speed, but the random buffering issue persists:

(Note: I wasn't able to patch 13-20 because a compile issue with video.c.)

I never have any buffering issues playing back a tvh recorded mpeg2 stream (which I think is somewhat telling).
LibreElec would be a better test environment as there is less going on, but my tests were on Android.

I tried a nightly Krypton about 4 days ago but I think it was in transition as I could not get the tvh pvr client to work at all.
