I heard that it was silly to buy 1080p, because cable companies do not support this. Is this true?
Also, is it necessary to buy some sort of connecting wire for HD, as opposed to the normal connection coming with the cable outlet? If one has basic cable, does one have to rent a box to get the HD on the major networks, e.g. if one is plugged into the wall outlet to avoid an A/B switch?
Thanks.
