I am finally getting around to setting up my home theater and noticed that my CATV box and TV have DVI jacks. Currently I'm using component cables and the 1080i and 720p pictures from cable HD are beautiful. Will an upgrade to DVI be worth the cable expense? Does DVI also carry the regular cable broadcast signals as well? As a side note, thanks Bob M. for the set up guide, well done. In it it is suggested that it may be best to possibly use svideo for simplicity sake. What effect will this have on the DVD picture if currently using component?
