If one is using the new video format RMVB, or the RealMedia Variable Bitrate file format, they will need to have the required software to read and use this file format. The kinds of software that support the RMVB file format are RealMedia Player and Real Alternative. Both of these kinds of software can be downloaded from the internet. If the user has a file in the RMVB format, but does not have the software to play this format, they can use certain software converters to convert the file into AVI or WAV or Mpeg file formats. One of the useful software converters is EO video.
