Hello Experts ... I have a Slingbox 500 connected to a Comcast DVR. It is connected with both HDMI and composite video cables, just like the instructions said. The first several times I used it from a hotel, everything worked great. Then, about a month ago, everything changed. I can connect, it plays the opening ad, then ... nothing. I can pop up my Comcast remote but no matter what I click ... nothing. So sound, no video. I rebooted the unit but (you guessed it) ... nothing.
I'm going out of town again in a couple of days and it would be nice to be able to take advantage of what I have recorded on my DVR.
Thanks in advance!
