I had this problem with chrome version Version 25.0.1364.97 m. I updated chrome to version 25.0.1364.160 m and the full screen videos seem to work fine with no frame rate problems. Press the "customize and control" button in the top right of the browser, then go to "About Google Chrome", and it will auto-update.
I just wanted to report this has fixed the issue for me as well.
I'm having the same issue as well with Google Chrome version 25.0.1364.152m on a Windows 7 PC, which is odd because I was able to watch videos with no problems on Saturday, 3/2. The video plays smoothly when its on the smaller, default size that is on the page, but as soon as I go fullscreen, its slows down considerably.
Go to Settings, then click on the link for Show advanced settings at the bottom of the options, then in Privacy section uncheck the box next to "Use a prediction service to help complete searches and URLs typed in the address bar".
I would really like Persona 4 Arena to just consist of the P3 and P4 universe and stay in the P4 Arena games and have P5 be its own separate thing. A Persona 4 Arena 2 would fill the fanservice needs nicely. I with FluxWaveZ in wanting a totally new cast, story, music, etc. I really hope Atlus keeps P5 as its own thing.
yeah, but getting 100% doesn't get you shit as far as I can tell so I wouldn't bother.
also, there's a choice after you beat aki for Chie's gag ending, don't forget.
I think both of those choices after you beat Akihiko lead to the gag ending.
The one that I missed when I was at 99% was the Margaret scene with Yu and seems to be the one people are missing a lot as well. There are two choices on that scene with Margaret as well so make sure you have a bookmark before that scene to make things easier.
