Dropped frames upon playback of your xvid "encodes"? It's probably due to packed bitstream output from the encoder ...

The fix is pretty simple, download this program

http://www.videohelp.com/tools/MPEG4_Modifier

open up your file, if it says packed bitstream, tick the box saying unpack. there's no re-encoding so it takes seconds to do this.

Voila!

You can also unpack with avidemux in Linux.

Is it possible to run on n900 itself? (and why not just add support for that to media player?)

It's arguably not a bug. Packed B-frames are a nonstandard invention to workaround bugs in some windows codecs.

Most encoding software wanrs against using packed b-frames, saying it's nonstandard and will reduce compatibility with hardware decoders. Yet people stupidly tick every box they can find...

There is a bug filed describing it though (and even the same workaround in one of the comments). I would imagine the media player can be configured to deal with this.

I've voted for it now, but there are only 5 others, so more are needed!

This might come out has a troll comment, so before the flames I want to tell I'm a very satisfied and happy N900 owner !

However...

I don't get it, we got a Cortex A8 @ 600Mhz that everyone says it's awesome in performance, however my 3 year old WM pda with a 520Mhz Marvell cpu plays most Divx/Xvid flawless without any hiccups that occur in the N900, using mplayer or the default Media Player...

All software side "issue" ? I mean i can play a regular 700Mb divx without much hiccups, but they do exist where they didn't in an older less powerful device...

Anyways like i said before, it's an awesome device and i did eventually watch the movies on my Tv with TVout, i just don't understand why like i said try not taking it has a troll comment...

Well MPlayer on N900 plays back packed b-frames fine.

The DSP codec doesn't know about packed B-frames. I'm guessing they just implemented a subset of the mpeg4 asp spec, and didn't research the utter crap real life tools produce.
