Fire TV Stick and Fire TV - HD channels jump/skip?

Hey gang,
I'd recent switched up to using the .m3u playlists (Big up to kens13 and crazed!!) and have been really enjoying the new setup. Faster to load, more easy to navigate, just over all a better experience. I did have one quick question though, I'd noticed that the HD versions of the channels seem to have a problem with skipping, for example; I'll be watching and it sounds and looks great, then without notice it'll jump back like 2-3 seconds and replay? I'm using the latest version of PerfectPlayer (1.4.6) and have tried different values in the new buffer feature, but it doesn't seem to alleviate the problem. Just thought I'd reach out to you guys because you rock and have never let me down!

Thanking you in advance,
Rocket77

Let's just say they know about the problem and appear to be working on it.
