I have some questions which I imagine rbinck or some other knowledgable person can answer. I have a Toshiba 34hf84 which has a resolution option of either 540p or 1080i; linked to a Comcast Motorola HD DVR.
1. I can see no difference when switching between the two resolutions - if there is a difference expected would it only be on fast motion scenes - I have only been comparing on freeze frame?
2. Regardless of the resolution setting, non-HD material on the HD channels seems to be a much brighter and sharper picture than the analogue SD equivalent when I do an A-B comparison. Is this because the up-conversion is already done by the TV station and therefore the HD cable signal is of better quality than the 480i analogue or digital SD signal?
