Just purchased a new digital cable box for my HDTV ready Toshiba. So I can now watch the pitifully few programs out there on my local cable carrier (Shaw). Last night I was watching CSI on High Def - with Dolby surround - how is this being broadcast in 1080i, 480p, or what? And is there any way to tell? One thing positive to say about the local cable company is that they have taken all High Def programming and no matter which network it is coming from , put it on one of three channels (and then fill up the remaining time with High Def films).
