That would be maximum loss of around half a second for MPEG Video. Isnt this acceptable ? Flickering screens.... Is this better with Sorensen ? Darling of the QT community.. Or realaudio ? www.mp3.com was rather successfull with streaming mp3s, I think. Maybe more as a social phenomenon. But I like the simplicity of mpeg_encode and mtvp and there are a lot of other MPEG Video players that can stream. Maybe it is like VHS and BETA, BETA is better, but VHS is what the people want, hopefully.. H.
