Simon,

I don't believe so although I could be wrong. As far as I know, the only thing you could set 800v4 for is 4:3, 16:9/1.78:1, and native format. It's just so that you can match the output format on the 800v4 to your display device.

Excessive? Never.
Emotion counts more than convention.
It's not a question of need, it's a question of want.
