I'm running openelec 4.0.7 (booting from usb) on my rpi. I'm using xbmc and tvheadend to watch satellite feed and I'm having some problems with the image quality on some SD channels:
I have no problems with HD channels or any other type of high def media.
I've tried disabling hardware acceleration and it doesn't change a thing.
The channels that I have problems with are all being transmitted in the same frequency and their format is mpeg-2.
So far I've been able to reproduce this problem on a number of devices all of them running linux or android.
Since I have no problems when running under Windows, is it safe to assume that this is a problem with the codec?
