I think my TV picture quality is sub-standard, it appears as if the depth of colours is reduced somehow. Sometimes things with gradient colours look stepped, kind of like when you look at photo's in 256 colours. Changing screen resolution has an affect, likewise swapping VGA for component connectivity @ 1080 looked better. Is it something to do with the scaler in XPMCE? What is the optimum resolution and refresh rate for PAL TV and DVD's? Using latest graphics drivers and NVidia decoder.
