Hi all. This is my first time posting here and I'm looking to buy my first Mac and I'm considering a 2.4ghz Mac Mini so that I may use it as a HTPC connected via HDMI to a 50" Samsung 720p 60hz Plasma. I want to be able to use both DVDs, media stored on the internal/external hard drive, networked media. My main question is will the Mac Mini display well on the 50" Plasma? The next question is I plan on using Plex. Does Plex support AVI, MP4, MKV files with ease? Thanks for any support all!
