XviD is the video codec - that is the system used to encode the compressed video information in the file. XviD is a free alternative to DIVX and is actually an open source codec. The 1.1.0-B2 is simply a version number, Version 1, sub-version(or revision) 1.0 the B normally means Beta - a prerelease version of the Codec that is still in testing. This version information applies to the encoder use to make the stream. The bitrate specifies how deep the compression is, the lower this is, the smaller your file will be, but also the quality will be lower. If you like, The bitrate is a measure of trade off between size and quality. The audio standard is using what it thinks is MPEG layer 3 - the same system as every Mp3 on your drive. Again - 130kps specifies the bitrate for the audio stream, which means exactly the same to the audio as it does to the video. The framerate is a measure of how many frames (descrete images used to make up the steps in a moving image sequence) are being played a minute. AVI files are a container or wrapper for video files which can contain many variations of video and audio codecs. It is quite simply the file type.
