hey guys i heard the latest patch allows for 5.1 audio streaming from pc files

does anyone know if the new patch allows anything else? like larger mp4 files or anything? i dont want to waste the time in creating large mp4 files (greater then 4gb) and not be able to play em on the ps3

havent found much info about this, and sony hasnt listed anything other then the XMB info in the patch notes.. even that 5.1 audio streaming was due to someone testing
