I know the difference between MPEG-2 and MPEG-4 encoding, but not about
transport streams. Anyone like to educate me on transport streams or give

It was not I who said that MPEG-2 transport streams were passe, nor was it

who thought that there were MPEG-4 transport streams. I deal with MPEG-4
all the time. In MPEG-2 transport streams.
you do not need to inform me, Craig. Your intentions need to be directed
to
