You lost me on that one - if it doesn't play in Media Player, how does it play from Archives? CuteTube internal player?
And, how the "doesn't play in "Media Player" manifest itself, exactly?
@pichlo- the cutetube player supports more video types than the stock player, from what I've seen. I tried playing AVIs and FLVs in the stock media player and got the "You can't play this type of file on this device" popup. I'm betting this is what happens to you also?
The nice thing is you can still play these files in cutetube, though. Is there a reason you need to play them in the default media player?
