I recently purchased a new 2012 mac mini w/ OSX 10.8.5. I updated the OS and the plugin for internet viewing on the web to the latest versions. I tried viewing my slingbox on the latest versions of Safari, Firefox, & Chrome....with all the same results. I get audio and no video, then after about 30 sec....nothing. I even tried switching Firefox to 32-bit mode to see if that helps and went thru all my file folders and deleted anything related to sling...but no.
I know the Slingbox HD-Pro is not the problem because I can view it fine from my PC laptop, iPhone, and iPad. If anyone has experienced this same issue, I would really appreciate any clues on how to resolve this. Thanks.
