Advertisements This question applies to any DVR. I'm not going to cross post this but would appreciate the answer as it applies to any unit including the S3 HD. I don't know if there is a generic answer or if the answer is different for different units. Obviously you wouldn't plan to use a HD DVR with a SD TV. Assume your HD TV has been taken into the shop for repairs and you're temporarily using an old set. Can you view recorded HD shows on a SD TV? Obviously you won't be watching in HD but will the unit do whatever downscaling or other black box magic that is required to display the picture. I know the units generally have S and component jacks so the set can by physically connected to the DVR.
