Often when I am watching my PRO-HD on my Mac or iPad the image will slowly lose vertical hold. A bar will appear near the top of the image and what should be the bottom of the image is now at the top (see image below).
Over time the image will continue to slowly roll down. If I disconnect and reconnect the image will return to normal but will start usually start rolling again. Slingbox support would not help me out unless I paid because my box is over a year old (thanks for the love Slingbox) but the person I chatted with said it is a problem with my cable box but this has happened on two different cable boxes.
Any help or insights will be very much appreciated.
