hi thanks for the info. the videos im downloading have no regional copyright issues and ive downloaded everything from home made videos to videos making cats with sill noises (purely for testing) as i said before somthing has changed on youtube and now the stock N900 player will not play them (the new downloads). if i use kmplayer and mplayer the video runs at an unwatchable framerate but the audio is good ok if a little stuttery. .surely if it was a problem with my device then my previously downloaded videos would not play right? plus another person has the same issue any advice or further investigation would be most helpful thanks
