Sorry, I as previously said, it's gonna take a LOT of work.

Typically, requests like these are looked down on, as developers in this community work for free.  Also developing usually takes a LOT of time, so asking someone to commit weeks of free time on a project is really asking too much.

If a developer is interested in such a thing, they would be working on it already.
Again, the PMP Mod AVC project is one of the best homebrew video players - if you're seriously in need of this, please contact those developers (though I doubt you'd gain much support).  The release thread for PMP Mod AVC can be found here: http://forums.ps2dev.org/viewtopic.php?t=4528

Sorry, but topic closed.
