Guys, thought I would post this because I have read a couple of threads on people having trouble with media not playing on the N900.

What people don't realise is that just because it says .avi doesn't mean that it is going to work! .avi is just the container, not the codec, think that's right - it's early so forgive me if it's wrong

The best solution for this, that I know of, is to re-code the file that you are trying to play. If you can't download the codecs etc. So if people are more comfortable changing the media rather than the device then...I have found a fantastic piece of software for this, that is very very easy to use from here.

This software will allow you to make a new file with whatever *specs* you want, so my suggestion is, have a play around, see what works on the device (contanier, video codec, audio codec, resolution, bit rate etc etc) and re-code all your media to work on the device, then you don't have to worry about copying stuff over and it not playing. Plus if you are not happy installing codecs and/or they are not avaliable it's another solution.

Hope this helps some people out (its helped me out loads), unfortunately it only works for windows, and you can't run it from a windows emu (WINE I think its called) in linux

EDIT: BTW you can change one type of media to another with this software as well, so say real player files don't work you can stick it in here and change it to .avi
