MPEG-1 and MPEG-2 are old, no argument about that. ;-)

You would hope so. It's just that I have yet to see such a thing. Every
codec I have ever tried has produced horrid results, with the exception
of MPEG-1 at really high bitrate, or whatever my DVD authoring software
is using (presumably MPEG-2, no idea what settings).

Now, see, actually *getting* 2 Mbit/sec of real data over the Internet
seems like an impressive feat on its own...
(My Internet connection is supposed to deliver 8 Mbit/sec, but you never
actually get anything approaching that. Plus you're probably talking
about the bitrate of the codec; there's all the framing overhead and so
forth on top of that to consider - although presumably if it's streaming
it'll be UDP, not TCP...)
