I have a channel that has this problem. The local NBC station changed
hands at the beginning of 2017 and since then the stream gets periodic
pixellation but only on NVidia. The pixellations are at exactly the same
places on Shield as with VDPAU on my low-end, $20 NVidia cards.
Apparently NVidia are using the same (faulty) software in the Shield as
they have used for years in the low-end GEForce 210.
These recordings play perfectly with software decoding, VAAPI, and
*_Raspberry Pi OpenMAX_*. ($30 Raspberry Pi works better than Shield?!?).
If you need a sample I can also provide one.
