Poor video quality is no fun at all. It's usually due to stressed or strained bandwidth on behalf of your Internet Service Provider and the bandwidth which your ISP has available for Internet connectivity.

If you're accessing us through a LAN (Local Area Network), you may experience similar problems as a result of the number of users and/or PCs on your LAN. This condition is almost always temporary, and if you try back later, you'll have experience better results.
