Real Caption Question


From: Janet Sylvia

We caption streaming video for Real media (using SMIL, RT and the associated RM file). The content is delivered from a Helix (Real) Streaming Server.

When the files are streamed, we can watch the video straight through from beginning to end and the captions remain perfectly in-sync. However, if we scan forward/backward, the captions fall terribly out of sync.

This does not happen if we play the files directly from a local desktop computer. We can scan forward/backward or play the video straight through -- all captions remain perfectly in-sync. The problem only occurs when the files are delivered from the streaming server.

Does anyone know of a solution to this?

PS: We are running the most recent version of Helix (Real) streaming server. We outsource captioning to Automatic Sync who provides us with the SMIL and RT files.

Thanks for your thoughts,
