INSTALL Lighttpd Streaming OR Apache mod_flvx Video Streaming ON MY SERVER?

The answer to that depends on personal preference. The apache mod is basically a rewrite of the mod for lighttpd and, from what I have seen, works pretty well. I have started using it in conjunction with mod auth token (similar to mod_secdownload for lighttpd) and it works pretty good. The only issue that I have had with the apache mod, however, is that it isn't universally supported yet by all players (like how lighttpd is). Most of the main ones support it though.
