Some while ago, I was able play video clips with 1080p resolution on my N8. Now on my N9 i couldn't play either 1080p or 720p, the 720p worked but with frame lag, even when testing Youtube html 5 trial www.youtube.com/html5 when i set the video 720p the lag is SUPER.

How come is the n8 better than n9 with playback? wasn't the n9 has much CPU power and better GPU!!!

Unless you have a good processor (desktop/laptop class), there is no way you can decode 720p smoothly.
So 720p and 1080p video decoding on ANY mobile, tablet and netbook has to be made by a specific hardware chip. Usually, this chip is part of the GPU, but having decoding for codec X with setting Y is hardware support, and has little to do with power.
It has to do with:
- hardware supporting it
- driver supporting it

N9 currently supports H.264 Baseline profile. It doesn't support Main and High profile yet (and maybe never). I don't know if it supports other codecs (or will).

Thanks for the reply, but in red part you're wrong i watched every series at 720p smoothly on my n8 like :

Fringe.S03E01.720p.HDTV.X264-DIMENSION.mkv 1.09gb
the.walking.dead.s01e02.720p.hdtv.x264-ctu.mkv 1.09gb

And some 1080p video clips and movie snaps

Yes because the N8 has a Broadcom BCM2727 GPU which support H.264 high profile.
The N8 does not decode video with CPU. Arm and Atom processors are not powerful enough to decode 720p (in general) and above with CPU only.

thanks for clearing that out

then there is no chance to play 720p,1080p on N9.

Maybe some driver update can enable it, but it's far from certain, sadly.
What I would do is use handbrake to convert 720p main/high profile to 720p base profile. You shouldn't loose quality (but should take more space), and you will be able to read it on your N9.
Conversion might take some time, though.

Might explain the lack of a HDMI out if playback isn't possible.

Shame.
