I just got my hd cable box today and all my channels including the HD ones are coming in at 480i resolution. Now the hd channels do look cripsper than the average cable channels but I can't change the resolution to anything but 480i stretch, zoom,normal, etc. I have a brand new hdtv : http://www.mitsubishi-tv.com/televis...ils.asp?id=182. Iv'e searched all the settings on the tv and cable box but theres no where to change the resolution. Any help would be appreaciated. Thanks.
