Hi all,Im new to the the HD subject but i understand that a TV needs to support HD to utilise the signal but will it yeild any improvement for non HD ready tv's? I have just purchased a Sony KF-42SX300 LCD rear projector and im a little upset that this TV has no support for it. Does the new Sky HD also only run on HD inputs or can we hook up to a scart for a better feed than the present crappy Sky feed thats full of digital noise? Anyone shed a little light? Thanks all.
