Hi, in my home I run Slingbox player on an Apple imac, an Android tablet and on a windows 7 PC. On the Apple only, the audio and video go out of sync. I do not observe this problem on the Android or Windows devices. Any idea why this happens? Sometimes the problem goes away if I hit the fastforward button on the Slingplayer Motorola set top box remote control icon. I have a Slingbox 500 with latest slingplayer installed on all devices.
