I've just upgrade my 32" tube to a 62" HM95 DLP. On my SD TiVo, the picture quality looks pretty bad. On a local channel commercial, the face was so blurred you couldn't even make out any features. I got the locals with the OTA and they look sharper, clear, and less blocky on upconverted SD. Would a change to HD TiVo help improve picture quality on the SD channels? Does the reciever upconvert or simply pass through the 480i?
