Ok I will try to answer question, it would be cool to sort this out.
First, when I go to options > filters > advanced, I cannot see any audio codec used. Quicktime Alternative is used. Here is the screenshot.

Then, when I render the mov file with Graphedit, I get a very strange graph. Here is the screenshot:

I do not understand anything in this graph. I don't get what is "color space converter", and I don't get how the input of the graph can send the audio directly to the output : "default direct sound device". Where is the splitter?? And why is Quicktime Alternative not showing up in this graph?
When copied to the hard drive, the mov file plays smoothly in BsPlayer.
This problem happens with EVERY mov file, but if you want to test the file, here it is:

Perhaps you could try to burn it to a CDRW to check if it plays badly.
One other note: the problem is ALMOST the same in Windows Media Player 10. The difference is that in BsPlayer, the video and sound is jerky. In WMP, the video is jerky, but the sound runs OK.
Now about the buffer options, I can't access them, the tab is not clickable! I don't understand why??
