I know that SD channels don't use even close to as much bandwidth as HD channels, but wouldn't deleting or combining redundant channels help to make room for other unique channels or increased PQ (decreased compression)? The movies channels all have an HD feed and an SD feed for example. ESPN, and NFL Network also come to mind, not to mention the upcoming FSN channels. Why broadcast a channel in HD and SD when a standard TV can display the HD channels just fine and someone with an HD set would be crazy not to use the HD feed.
