[mythtvnz] VDPAU and TV3?

[Jonathan Hoskin]

I wouldn't have thought your TV would cause the issues - AFAIK the display
resolution coming out of the PC is scaled by your video card and would
remain constant across channel changes.

I have personally had TV3 problems when my UHF signal strength was a bit
weak (< 30%) from too many extension cables, splitters, and bad wiring
inline.
