Random buffering only on certain channels

[1sikguy]

About 10 days ago, everything was working fine. Then ... I started to get immediate and excessive buffering on many
of my regular channels. Buffering on AMC, CNN, ESPN, Film4, Chiller, Headline News, SKY Atlantic, ESPN, National Geographic, Spike TV, and FXX.
All other channels play fine, only a small number have this buffering problem.
Using Openelec 6.0.3/KODI 15.2/Stalker Client 0.8.4
I have no problem loading the channels, they load fine.

This problem happened on its own...I made no setting changes till it happened. These are some of the things I have tried:

1. Changed my Postal
2. Performed an IPTV reset
3. Upgraded from Openelec 6.03/KODI 15.2 to Openelec 6.95/KODI 16.1
4. Deleted the TV29.db file and it has reloaded
5. Tried switching to the Google DNS servers
6. Removed PVR Stalker client and installed the Stalker Plus addon. Had the same buffering on the same channels in PLUS

Nothing has worked

Need some community help with this one..
