Comcast will have the HDTV cable ready for my area 11/01/02. For those of you who have comcast HDTV cable, I have a question. Does the set top box convert 720p to 1080i? I am interested because I bought a toshiba 50h81 widescreen hdtv a year a go. how will Espn hdtv in 720p look on my screen? I am newbie with hdtv so I apologize in advance for my ignorance on the technical ignorance. thanks!
