RealMedia Container Format

The RealFormat SDK supports the RealMedia format as defined
in
the documentation of the RealFormat SDK. There is indeed a
legacy
format from around the 1995 timeframe which pre-dates the
RealMedia
format, and the RealFormat SDK does not support that format.
This
is sometimes referred to as the old .ra format. (Even though
newer
encoders sometimes write out to a .ra file but these .ra
files are
in the regular RealMedia format).

But content created around 1998 should have been in the
RealMedia format, which the RealFormat SDK should support.
