I tested the Slingbox HD Pro in my family room by hooking to my network and then pushing the information to my TV using HDMI from my Media PC. The picture was no different than the Direct Cable Tuner.
However, I had it installed at my son's college apartment with high speed uplink and download and the HD picture looks terrible. is this typical or do I need to reset up the unit at the new location??
I am going to take it back since it doesn't provide realy 1080I quality.
