I can hear the Audio clearly, but no video. I notice that when I change to 1280X720 or higher, the bit ratedrops of to less than 100kbps. At 640X480 or lower, the bit rate is greater than 3500kbps. Prior to a couple of days ago, it was working fine. The only thing that change was an update to my McFee Total Protection antivirus software. Thinking that there may have been a change in the software permissions through the firewall, I checked those settings and found that the slingbox has full access. Any Suggestions?
