WideStream Download Manager

Minor bug, when setting up for downlaoding a HTTP-FLV stream some minutes
before it starts so that Widestream will retry until the stream starts, the
file containes multiple "FLV headers", I guess one for each retry.
That is, FLV followed by the "ordinary stuff" (I guess), a total of 13
bytes.
THe file cannot be played by the FLV players I have, but obviously easy to
hex-edit, delete all but the last one. Then it "works".
However, mplayer cannot index the file to jump forwards (instead retuirns
to start) but that might be, probably another issue, I have not looked into
this one.

Gunnar (thanks for the code, I'm an (old) assembly man, even C is "a little
too high level", but I will attack C# and .NET, add some features,
scheduling for streams like that)
