I have had it with the 09 Mini and stuttering Flash. Plex is great, we've been using it on Hulu, NBC's website, etc but the stuttering makes it unwatchable. The problem is its the Mac, not necessarily Adobe. Boot into either Vista or Win7 and have the exact same problems. I have 6 other machines in the house ranging from much slower(2.2ghz Celeron off core2 architecture) to my much much faster C2Q at 3.3ghz. None of them this issue. Last night I downloaded Hulu Desktop at someones recommendation and it played decent, would stutter every 1 minute or so but nothing bad. Sit down today to watch something, its 10x worse than watching it over Plex. I've rebooted, reloaded, upgraded Flash, put in 3 gigs of ram...you name it. Its the box IMO and that makes no sense because why does it happen in Vista/7 via Bootcamp? FWIW it plays MKV's and MP4's with no problem at all....I never had this problem on my previous Mini. The Mini is in our bedroom connected to a 47" Westinghouse 1080p display via DVI. I run it at 1280x720 because from our viewing distance its way too tough to see the 1920x1080. I can turn it down to low or medium quality in Hulu, no difference. In fact it seems worse the lower it goes.
