Hello, sorry for the weird title, it's hard to explain for me. My problem occurs not only for my usual Firefox, it occurs even after a complete Firefox refresh, without any Addons or changings in the options. It's just the Firefox, IE and Opera don't have that problem. I have Win7. I can play most movieclips (Streams) as intended. That means I can for example click the progress bar to an unbuffered point, the player skips to that location and I can watch from there. That does not work with every clip. Some clips (it's always the same pages but I cannot give you an example here) don't work that way. I can skip to a later part, yes. But only if the player has already buffered to that point. If it's in the unbuffered part, I cannot jump there. Any advice?
