I have posted this in another thread but can't remember which one. Piece of advice.
The best way to watch a video stream is if you can to be hardwired from your cable modem/router.
Streaming from wireless can be decent but usually packets of data get dropped and it is far more inconsistent than being hard wired.
So when you hook up your laptop/desktop to a TV either through VGA, DVI or HDMI have that computer hardwired with an ethernet cable. It will make a world of difference.
