You may need to increase your broadband Internet speed. Using Netflix as an example, their requirements may say that up to 3 Mb/s is adequate, but according to http://hometheater.about.com/o.....x-Vudu.htm you actually need 4 or 5 Mb/s to enjoy HD video content. Otherwise, the stream will be adjusted downward to a lower resolution that is grainy and not acceptable to you.
