Wild media server (UPnP, DLNA, HTTP)

First of all this media server rocks. I search and search Internet about 2 weeks how can I stream my movies (with subs) to my Sony Bravia KDL EX710. Last night I found PS3 Media Server, Seriivo and Nero Home4 but no one as good as Wild Media Server.


Now I've explaining my problem; yes WMS streaming AVCHD's, mkv's, DivX's to Sony with subtitle. But there is a little annoying bad detail. Videos with subtitles that I want to watch skipping per 30 seconds. This skipping leading 0,5 seconds sometimes longer. Mean with "to skip" is short freezings .

Why? Can I trim it?

I'm waiting.
How can I reduce the latency?

"Transfer Data Buffer Size For This Device"

I think this option may be solution. Could I increase this value?
