Why is the quality poor for audio, video, or both?
A. The two likeliest reasons are that the actual media file was encoded to use low-quality settings or that network congestion is causing packets to drop from the stream. To learn which of these scenarios is true in your case, play a local copy of the file in video playback software, such as VLC. If the local copy of your media file plays smoothly and at an acceptable quality, you can assume that packet loss was the original problem and you can take steps to apply quality-of-service (QoS) bandwidth tuning in your network.
