Hi, so I'm wondering if anyone out there has their Apple TV working without a lag when they mirror their devices, especially a Mac Pro since that's what I'm having the most trouble with. I assume my Internet is fast enough because I can stream video on the Apple TV or Mac Pro, but when I try stream something from the Mac Pro TO Apple TV it will lag or freeze periodically. Depending on what it is it might be worse, ie YouTube is usually worse. Just in case, I connected my ISP rental router/modem to the Apple TV thinking the wifi might be the problem. A little better but still lags and freezes! Even though I need to use my ISP router because I have DSL, would it be helpful to get an airport express to setup my home network? Any questions? Suggestions? I'm nearing my wits end with this because I've never had such issues with apple products before!
