== Disambiguation ==
 
It's not entirely clear whether the term/concept ''Packetized Elementary Stream'' is used with both MPEG-1 and MPEG-2, or just MPEG-2. Wikipedia's ''Packetized Elementary Stream'' article clearly implies it's just MPEG-2, but Wikipedia's ''MPEG-1'' article says it's used with MPEG-1. In any case, we need a name for all the single-stream MPEG-1 .mpg files that do not use the [[MPEG Program Stream]] format.
 
 
Some sources (e.g. Wikipedia) seem to distinguish between a raw ''Elementary Stream'' (ES), and a ''Packetized Elementary Stream'' (PES). Others (e.g. [[PRONOM]]) seem to use the term ''Elementary Stream'' to refer to a Packetized Elementary Stream.

A Packetized Elementary Stream (PES) is the basic format by which streams of MPEG-1 or MPEG-2 audio or video, and other content such as subtitles, are stored within certain formats such as MPEG Program Stream.

A DVD has its content in a whole series of these. The VobSub program grabs the PES packets on a DVD that represent subtitles.
