Just recently, I've been having difficulty streaming programs. The program will start, then after a few seconds, stop, and the little circle appears, then a further second or so, and the whole process goes on and on like this, in fits and starts! The message from BBC iplayer is "Insufficient bandwidth to stream this program ...." It's the same issue with YouTube and similar. What's the problem? Where has my previously sufficient bandwidth gone? How do I increase this once again to a workable size? My system is both modern (6 months old) and powerful too! Any help would be appreciated!
Try lotvic's link. There is a faur amount of valid discussion going on.
In the mean time, if it plays for a couple fo seconds then pauses for a couple of seconds, then plays again (repeat to fade!) a short term fix is the start playing the file, pause it for a couple of minutes then resume playing it. While the file is paused it will continue downloading and you will build up a buffer.
