I have installed the flash player on my windows 7 system, i was just considering that it can be happen because of the bandwidth issues . I was surfing the Internet at very limited data plan to 256 kb/sec. But had it when I work upon the windows xp as well. I have noticed that a site where I could be able to select low speed, medium speed or high speed bandwith. I have selected the low speed 265 kbps and the video played flawlessly without restricting and starting.
