Hi Glenn - I don't have the URL to hand, but realtext can be streamed (though only through RTP, not from HTTP afaik) : RealText has <required>...</required> tags Tealtext manual : "Use these tags to enclose text that must be delivered to RealPlayer under any circumstance. During extremely adverse network conditions, RealSystem will halt the presentation if necessary rather than drop the text." In practice, the bandwidth for streamed text is so low this would never realistically happen from a Helix / Realserver box. But these systems *definitely* stream the text too, whereas HTTP I guess will deliver the whole file verbatim - I don't have a big enough example to time it :-) Not too sure about SAMI though - it seems to be a bolt-on, and is handled by the player rather than the server afaik (ie, using a ?SAMI=url or by adding to the media directory). Maybe I'll sniff my server logs and see what the timing of requests is. Cheersn Neil Smith.
