There seems to be 2 different issues with Live TV streams.
I struck the issue testing with introduction of newer Kernel for S90SX / W / D Socs.
I also had issues with my Vim3 , Vim3L
My issue is only on one MUX and the HD channels.
I only get the issue of Pullup Correction 2 (PC2) with a poor video quality.
However I tested another members recorded TVH Channel and i got Pixelation on
ALL versions of CE with this recording
Including CE Stable 9.2.1.
The Pixelation issue seems to have been eliminated using new Kernel.
It does not result in perfect playback with these certain TV Streams.
So we have 2 different issues.
