Audio Sync Issues, tried everything PLZ HELP !!

[naamloosmusic]

Hey there

I have always been using the PS3 Media Server, and i must say it has always been amazingly helpful and pure joy to use BUT... i am having some problems lately.
I recently decided to reinstall my PC since i had some problems, and for some reason, i can't get it to stream properly.

I just reinstalled Windows 7 Professional (64bit), i have ALL the latest drivers/updates, i reinstalled PMS, and i can't get it to work properly.

For some reason it streams without a problem, the subtitles work, but the audio is out of sync.
I tried disabling the "A/V sync alternative method" and enabling "Force framerate parsed from FFmpeg", but no results.
So i moved up the tsMuxeR and FFmpeg engine, and it seems to work flawlessly then but i seem to have no subtitles.

What can i do as it used to work fine without ANY problems, please help!!!

Here's a little information about my PC / setup:

CPU: Intel I7 2600k @ 4,44 ghz
