Sad thing is it's just a horribly done upscale from dvd by whoever issued this "blu-ray". DVD has more details, don't bother downloading this one (no disrespect to topic starter)
This is an official release, you can find it everywhere, this isn't an upscale, it was released in 2009 after the DVD and audio CD versions, there is extra content only available in Blu-Ray too. https://www.blu-ray.com/movies/Paramore-The-Final-Riot-Blu-ray/3986/
I know it's an official disc and realize that upscale wasn't done by you (or any casual Paramore fan for that matter). The manufacturer/label/record company (call it whatever you like) simply took an SD VIDEO source, threw in 5.1 mix ( the only real difference between this issue and DVD) and decided everyone will be happy with blurry image. It was never my intention to offend you, we all know it's not your fault this good concert got such an ugly blu-ray treatment (picture quality wise, the sound is still good).
