ISSUES

The differences between various container formats arise from five main issues:
# Popularity; how widely supported a container is. This is the reason that the AVI format is still the most popular format
# Overhead. This is the difference in file-size between two files with the same content in a different container. For a two-hour film, when in AVI, the file may be up to 10MB larger than when in Matroska.
# Support for advanced codec functionality. Older formats such as AVI do not support new codec features like B-frame s, VBR audio, VFR natively, although the format may be "hacked" to add support, creating compatibility problems.
# Support for advanced content, such as chapters, subtitles, meta-tags, user-data.
# Support of Streaming Media
