Guys.my frnd has a broadband line 360kb=45KB.With this line can easily see the youtube videos in 480p.just gets buffer for 1-3 sec and no buffer next 3-4 minitues.I have 512kb=64KB line where it is almost impossible for me to watch video in 360p.I usually see in 240p.I get this speed constant always.I m amazed to see it.
Do u guys,have any explanation of this problem?

Other people on your home network, or your ISP sucks and isn't providing you with adequate speeds as advertised, or something on your PC is sucking down all bandwidth.
