when i upload a video to youtube at the moment the upload jumps way ahead (about 20% for a 800mb file) when the upload starts and then it freezes on the percentage that it jumps to. I have never had this problem before and it is really getting on my nerves, it never used to happen and i have also tried uploading other videos and i still get the same problem. If anybody has any idea how to fix this problem please help me, i would be very grateful
