[MEncoder-users] MPEG2 aspect 2 or 3

[TAJTHY Tamás]

Dear List,

Running mencoder it writes some information to the screen. There is one like:

„VIDEO:  MPEG2  720x576  (aspect 3)  25.000 fps  …"
... or ...
„VIDEO:  MPEG2  720x576  (aspect 2)  25.000 fps  …"

Can somebody explain what is the difference? Is it the DAR flag
(anamorphic scaling)? I suppouse aspect 3 can be the 16:9 DAR flag. Am
I right?

Thanx!
