I'll be viewing in an area with no wifi and only vehicle power supplies. I would like to watch live sports with my phone and display on my laptop screen. First, what are the upload speed requirements for slingbox and how do I check my speed at home. Second can I simply buy the $40 HDMI cable and connect from my Droid X to the HDMI slot on my computer to view the Slingbox feed on the computer screen? What other hardware, software or apps are required ( I am aware of the Real HDMI and slingbox apps)? Thanks.
