I have managed to answer this myslef but could help others ...dont using any other browser except Firefox ..even though they suggest certain browsers should be compatible ... I found three that wasnt ( even with the plug ins installed and all updated )
My only other question is that how does the HDMI plug work on this unit ? Ok its a feed in I know but at present this is connected direct to my TV if I connect to the sling how do I then connect to TV as an output ?
I understand that you want to know if the Slingbox PRO does work with the HDMI input.
As a matter of fact, none of the Slingbox models will work with the HDMI cable. The port on the back of the Slingbox PRO does work with the HD Connect cable, which has nothing to do with the HDMI Cable. The following links will provide you with all the information about this situation and some other information that might be useful for you:
Hope this helps.
