i had a similar issue after a reflash - no audio video or photos showed up. i managed to cure it by deleting .cache

open terminal then

rm -rf .cache

you'll get the yellow banner saying "scanning new meida" or similar next time u try to access media player/photos and u should be back in business.

I just tried this and still nothing in media player or photos.

Thanks any way!

i gave .thumbnails the same treatment but was of the impression it was .cache that sorted it. so maybe try this too.

other possibility is that some peice of media is trippin it up and making it go wrong. maybe try removing anything you added just prior to it breaking.

Just tried .thumbnails with the same result as before!

Their was an update to Maemo which resulted with this problem. thats all I can think which has changed! I remember receiving the update and then shortly after noticing things going missing!

Well I am buggered if I can sort this out! Is their any way of returning my phone to the factory out of the box condition? I have flashed it twice but it still retains files!

I have a problem kinda like that. I have pictures/videos that I took with the n900 a while ago, and the will not play/show in the media player or picture viewer. (They do show in in the file manager)
So here is the kicker....I took a few more pictures a few days ago, and the will display in the photo player. Here's the next strange thing.... I have the Personal Photo Frame on one of my desktops, and it shows "All" of my pictures.
I think it may have something to do with (And I could be way off here) changing my camera settings from wide-screen to High Resolution. At lease that is when I notice it started....I think. So at this point the picture viewer will only show pictures that are in high resolution.

Found the fix...So I put the camera back into widescreen mode, and rebooted. Now all the old pictures show and the new ones as well.

So I went back into the camera settings and changed it back to High then went to see if I could still view the pictures (I could)
Once that was done I rebooted again to see if it would keep and it did

Dont know if this problem is related to yours but hope it might give you a few ideas.

RIGHT I have solved the problem!!! It is quite simple, if all else fails hard reset everything using this tutorial:

It's a pity you had to do it that way rather than actually finding what the actual problem was, but glad you managed to fix it.

Did this and all is back to normal! The hard reset is in two parts firstly re-flashing the OS and secondly resetting the Mass Memory! It was only when I reset the Mass Storage it solved my problem!
