dont know if this can be worth a penny but using previous image 8.2.2.3 had same problem, on s912 and s905x/w box but then moved data to internal SD and problem disappeared, even with hw acceleration enabled. using a class 10 SD card, been testing for about 1 hour now, continuously switching channels and it's as smooth as velvet which makes me thinking it may be a hw problem not up for business rather than related to the image. will try on latest release soon.

This version plays PVR streams well, but recorded HD files are very jumpy - which is a regression from 8.90.6. Tried a few settings and couldnt get any improvement.

Edit: can confirm that setting fallback framerate to 50hz solves this.

Reverted back to 8.90.6 as this version seemed less stable.
