Hi Peter,

Attached some previous information I had found a while back. The patches 
will likely not apply, and I expect folks already fixed the problems, 
but I have not investigated them down to see :(.

As a summary, it appeared, at least when I was testing, that the vlc 
plugin was actually downloading each file twice. Once via vlc playing it 
natively and once as it downloaded it to Mozilla's cache. By hacking a 
bit at the code, I stopped the cache download and that was a big benefit 
here while testing over slow links.

As I do not know the plugin interface, and spent only some time trying 
to understand it, I know my patches were wrong. So other than possibly 
helping to understand what you are finding, you may take it all with a 
grain of salt :).

take care,
JES
