So here's what I use my TV for. I watch DVDs about 75% of the time, and play Xbox/PS2/Dreamcast 10% of the time and watch TV the rest of the time. Mostly watch shows like Dr. Phil, things that probably aren'td HD. I have HBO and would watch HBO in hi-def, but don't know that it would be that big of a deal once the wow factor of the picture blew over. So here's my question: Would I notice any difference in picture quality if I went with a nice HDTV (regular tube, like the Sony KD-36XS955) versus a nice standard def tube like the Sony KV-36FS120 when using DVDs or playing the Xbox/PS2?
