I'm not shure what you mean with the term "CODEC" here.

The spec of MPEG 1 or 2 is not floating, it's (rock) solid.

The only thing that could (should) vary are the parameters used to 
encode the movie, like resolution, bitrate, GOP structure, etc.
So it's not important which programm made the MPEG stream as long as the 
used parameters were correct.

To look inside the parameters of an MPEG stream,
i use the Bitrate Viewer BV:

The free version should give you enough information.
