It's working for me. Maybe the commit I made this week end fixed it.
Can you try with today version of CVS and let me know if it's still broken
for you.

Yes, there are 2 connections made. The first connection is to attempt to 
detect what kind of streaming to use, this response to this request will
content the mime-type. Depending on the another connection is made
using the appropriate protocol. In the case of progressive streaming
(from an HTTP server) the same request is made and kept open.
Sure an optimization on this can be done. But for now I want
make everything working to turn the streaming ON by default so
every body can enjoy this long time waiting feature :)
