Thanks very much.

By video I meant free to air but obviously what we're receiving in Australia is vastly different from what you're getting in the UK and therefore my question was inappropriate.

Here we have HD digital broadcasts in 720p and 1080i and in my case these are being sent via DVI into a Marantz S3; I'm trying to ascertain if a processor such as the Crystalio will improve what the Marantz is putting out.

Regards
