Helium browser , opera 12, fennec latest version or digia web and WHY??

flash 10.1.98.88 nokia real for n900 yes and with hex editor emulated v12 but and with cpu 1150 and dsp 600mhz

some 360p videos well and others bad , with lag. Sound ok and video slow

480p Nothing horrible playing, very very very slow

Why more navigators?, If with microb is the more faster and stable but flash videos very lag.

N900 default with flash 9 240p videos ok and other resolutions very bad,

n900 modified 1150mhz 600dsp , flash 10 and libraries and codecs for 720p and more browsers 240ok others resolutions very bad

where is the change?, Nothing changed in flash videos in four years

First to resolve it.
