I previously used my Ipad 2 which I would connect to Apple TV to watch my slingbox on my TV. Always worked perfectly. Now I have a new Ipad Pro 12.7 inches set up in the same manner. Even though I can watch slingbox on the ipad with no issues, when I connect to Apple TV (gen 4), picture and sound stutter so badly it is unwatchable. If I try the same thing with my spouse's Ipad Pro (9 inch), it works perfectly connected to the TV via Apple TV.
One more piece to the puzzle: the Ipad Pro 12.7 does not have the same stutter issue when I connect it to a different TV using Roku. Plays just fine.
Again, the slingbox always plays fine on the ipad Pro. Any suggestions how to fix this would be greatly appreciated. Thanks.
