You'll be able to view videos in ur phone's browser only if it supports flash, which i suspect it doesn't. But you can play the the video streaming sites (rtsp://), if ur phone's media player supports it.
Plus to know edge settings of ur connection, contact ur service provider's customer care, he will either send you or tell you the way to get it. If you are unable to get it, request it here, i remember almost half of network operator's gprs settings
