I just got my Toshiba 46H83 delivered and I'm having problems with the HD cable tuner. I connected the cable line to the tv and then connected the out screw on the tv to the HD box. I then connected the green, blue, and red cable into the corresponding places on the tv and the box. I set the video on the tv to "HD Colorstream 1" which is what I had connected the box to. The channels show up, but the normal channels are stretched to fit the widescreen. Needless to say, it doesn't look pretty. I also tried connecting the cable line directly to the HD box, but the same result happens. There is no cable out screw on the box. Unfortunately, when you set the video feed to "HD Colorstream" you can't change the size of the picture between normal and theaterwide. The HD box has DVI and S-Cable outlets, so would my problem be solved if I went out and got one of those cables? Let me know if more info is needed.
