I use Mencoder to MP4 movie file into sd with the hd, using nuveo player, I encountered a serious problem, changing to sd video, no matter what position to drag the movie will start playing, HD part Can not fast forward, I have set up lighttpd for "mp4"

Please tell me where wrong??

I replied to you maybe 10 times, and I have enough.
This is last time I do that and each next question about it will be ignored or post removed.

You have player set to use lighttpd streaming.
But HD alternative video is not set to use lighttpd.
It even cannot use lighttpd as HD videos are located in different FLV folder, while lighttpd points to FLV folder only to play videos from.

To correct it - lighttpd ini settings must bechanged, so it could use other than FLV folders as well,
then playlist php file should be updated for video URLs according to lighttpd changes.

That's my final answer.
If you're not able to understand it or do it yourself - hire a programmer or order custom service.

We as Nuevolab cannot be responsible how lighttpd is set until it is not installed by us.
