Hi every body I'm new to the site and I've been reading for days all the info on here well not all of it. I just can't find anything similar to my problem. I reacently bought a Sammy 46A650. got it all hooked up PQ is amazing on dvd @ 720x 480. but when i watch direct tv my grays and blacks have what look like shadows. Also sometimes I get either trails or motion blur behinde people. It doesn't have to be an action scene either they could be just walking and I'll get a quick trail or blur. I've tried some of the adjustments found in the share your custom settings page which did wonders for my dvds just not much for Directtv. I'm new to the game hoping to get some suggetions. Sorry if I don't have the proper info listed. Just let me know and I will post it. Thanks
