From what I gather, none of these are supplied on the PSP Browser (it is Sony afterall).

So why does my PSP prompt me to 'press ok for help with installing Realplayer (which does nothing) when I try to access a Realplayer stream?

Im deeply disappointed by Sonys lack of support for customisable content (not necessarily things that allow playing ISO/Emulators, but IRC/messaging software and other things which the PSP would be ideal for.

Would be something if they would allow people to develop their own browsers (which could have software compatibility).

Bleh Sony
