I have 2 nokia 5800s and when i run Iplayer site and try to watch it (via wifi) the video shows but there is no sound. My sound is working on other songs downloaded videos etc. I However I can only hear it when I download the video but its annoying to keep on downloading videos.Whats my problem? I already downloaded a license for the video so thats not it. This problem is on both and they are fully updated.
