Possibly my setup and experience is a peculiar situation, but this may be something to watch if a standalone VP is involved.
At some point I 'll try upgrading the VP firmware and see what happens.
I wasn't addressing a situation where you're adding more processing to the video chain. I've always thought the best PQ is obtained by keeping the processing within one component. (Personally, I think the old adage- "too many cooks spoil the broth" - should have a corollary: "Too many processors craps up the signal."
It seems to me that people report more issues with adding those processors than they are worth. Just my impression. But if I were going to add one, it seems to me that you'd want to send everything source direct and let it do all
the work. With any component where I don't
want it to do the processing, I would bypass the external processor completely.
