Thanks a lot for your reply. Check it out on Unix ;-)

Or a "metafile" in Reallingo.

Yeah. But what do you do with those people who dont have a mp3 Player,
that supports video ? Imagine a world with an Apple email system and a
Wintel system.. Maybe I am oversimplifying things, but my frist internet
experiences were Kermit and VM/CMS, thats why I say "What doesnt run on
Unix isnt in the world".

Yeah, if you do it every day.

Ah, the Media Player is phantastic, plays my simple m3u fake lists without
any problem. I hope dear and noble Bill supports the extension mxu
(formerly mgu) in his next version !!

And the others will follow...

Yeah, I see that we are doing the same kind of experiments, thanks again
for the feedback ;-)

Well, 256 is 256..

I did it with much less bandwidth, just to prove that MPEG streaming can
work even over modem. And I compared MPEG and REAL in quality. There are
differences, but they are not so important.

This is a great program. The only GUI tool, that comes near avi2mp1.exe.
But (!), you should really try to get the original mpeg_encode. There you
have a parameter file with *much* more freedom for your experiments. The
authors of avi2mp1 etc had VCD etc in mind, not streaming. Might change
soon, if we tell more people how much *fun* (in the Carla Bley
sense) such experiments can be ;-)

Best,
