So I noticed that youtube recently added the 1080p and 720p choices to their videos, and I was pretty excited until I realized I couldn't play any of them. When I click the watch in hd 1080p button, not only does my browser lag, but it makes anything I do on the computer lag (including when I have nothing but my browser running). On the videos where I have the option of 1080 or 720, if I keep it at 720 the quality is horrible. (The HD videos without the 1080p option play fine, and have no lag). I have a MacBook Pro Processor: 2.16 GHz Intel Core Duo Memory: 2 GB 667 MHz DDR2 SDRAM I just updated my mac with the snow leopard software, adobe flash player 10... is there anything I can do? I am not a computer whiz, so try and keep advice dumbed down a bit? EDIT: so youtube updated their HD stuff a day after I posted this question, but I am still unable to watch any HD videos in 1080p. 720p works fine, but I guess I'm just confused as to why I can't play the 1080??
