Toshiba TZ50V61 50-Inch Projection TV
Digital Compression
This &quot;blocking&quot; effect, known as pixeling, is the result of over compression of the digital signal by your DBS provider DIRECTV.  This problem will eventually improve as DIRECTV launches more DBS satellites.  I  find EchoStar's DISH Network to be far superior as far as compression  issues are concerened.  Currently, EchoStar has more bandwith, therefore  requiring less compression.  I have a DISH Network receiver connected to my  62&quot; Toshiba projection TV set via S-Video and am very pleased with the  picture quality.
