hey all!

I own an archos av500 100gb model. It has been working perfectly no hardware defects what so ever! But for some reason, some videos (mostly downloaded from the internet) have a slight audio delay when i play them. It is really slight but still id like it to be in perfect sync. The wierd thing is that when i play them on my pc they are in perfect sync! WHat does this mean how can i fix this?

btw they are all either divx or xvid.

thanks

Alex.
