I have a 13" 2012 MBP (core i5, 2.5ghz, 8gb ram). When I try to airplay (screen mirror full screen streaming videos), it plays mostly fine, but it will get a little bit laggy every few minutes. I dont even know if it technically "drop" frames, but it will freeze for 1-2 seconds, and then play really fast for the next second to catch up. Audio works fine. Any idea how I can fix this? Is it a problem with the Mac's processing power or possibly my router or network settings? I MBP is wireless, ATV is wired. Thanks.
