I have Dish and a 508 and 3 301 receivers. I would like to replace one of the 301s with an 811. I have a Mitsubishi 62 inh DLP and am wondering if I would get sharper SD channels from Dish using the component or DVI versus the S-video output from the 301? Also would Dish activate the 811 without the HD package, I get my HD channels OTA thru the tv tuner.
