I am thinking about buying an Apple TV and need to know a few things - I hope you guys can help me. I do know a bit about computer hardware, but when it comes to audio I am a total noob. First the hardware I already got: 24'' LG Computer Screen (from my gaming PC) with hdmi and dvi in and a 3.5 headphone jack out (never used that one) My dads old B&O Soundsystem (about 30 years old ^^) - it got the stereo in (the red and white cable) and I got a kit to get it to headphone jack Macbook Pro late 2010 Macbook Pro early 2011 (gf's) What I want to do with the setup: I thought I connect the ATV via hdmi to the LG and the B&O to the headphone jack. In my fantasy I would/could use the display for work, stream movies (Airplay Mirroring and AirParrot for the 2010) and listen to music from the Sound System. So before I buy the ATV I wanted to ask: 1. Is there a flaw in my idea - which part could make problems? 2. How about Airplay Mirroring of HD movies - does it work or is the lag noticeable? Thanks for your help!
