Kinda ironic that it can't play arabic songs don't you think? :P

I've been digging through mafw's code, and stumbled across this in the changelog:
* Disable native flags in playbin2 temporarily since this is causing
trouble with some videos. Also, allow videos with resolution
up to 848x576.
* Changed highest resolution for fremantle

So I'm guessing that limit can be removed, unfortunately, grepping for 848 returns no results, so I'll have to look where it's limited.
