I have been reading in this forum with interest about the various ways of improving the picture from Sky. The 2 most common suggestions are to use a JA Scart to VGA converter or an Iscan Ultra. I am thinking of buying a 42" plasma but picture from sky must be top quality. I have heard of companies that mod the sky+ box to provide an SDI output. Would this connection make a noticeable difference when connected to a suitable plasma?? Am I correct that this connection frees the bandwith for channels in someway??
