I *suppose* that batterypatch may not be affecting, as it *supposedly* only kicks in when locking/unlocking the N900.

As for speedpatch. Not even the author has a clue about what it does, but Maemo has (built-in) a pretty sophisticated system for classifying tasks in groups, which speedpatch probably "rapes", so to speak.

The stock player uses hardware-accelerated modules for *some* formats/codecs. No idea about FLV.

Other than that, no idea. The only videos I play with my N900 are re-encoded MP4 videos ripped off of Youtube (children's stuff), which are crappy anyway but play smoothly enough
