Question for the lucky few who already have their rMB. I'm still debating whether to order the machine, but the following is a huge dealbreaker for me. (and I can't test this myself in the store) So if you have an rMB, it would be appreciated if you could take the time to test these scenarios for me: 1. Can rMB play 1080p MKV content smoothly? (no lag, no choppiness) 2. Can rMB stream 1080p MKV content to an AppleTV using Beamer? Thanks in advance!
