I've just received my LG LST-3410A HDTV tuner/hard disk recorder, but probably won't be hooking it up until next week. I'm going to run its DVI output directly to my Sharp DLP projector, because for now it will be my only HD source, combined with the fact that the 990's on screen messages are not available on DVI. If I switched through the 990, using the DVI signal path, I'd have to pull up the 990's menu in order to get its screen display by changing the device input selection for the tuner. What I will do at intitial setup is specify the input on the 990 for the tuner as component. Then all I have to do to get 990 screen messages, is switch source selection at the projector, which is a simple one step operation.
