My speed test w/ my internet service provider indicates I'm getting 4MBS. But when I connect to sling box, the optimization rate shows around 1.5MBS. What does the sling box MBS represent? Can I increase it? (already tried all optimization options). Will it impact HD streaming to my TV? Computer is a Toshiba laptop w/ Intel i5 chip running at 2.67 Ghz, w/ 4 Gb ram and an ATI mobility Radeon HD5650 graphics. Internet is connected wirelessly to computer, but like I said, speed test show 4 MBS, so it looks like I'm getting 4MBS to the computer. Sling box is a Pro HD.
