Hi elupus,
first of all let me thank you for putting so much work into the development of mplayer.dll

But I am sorry to say I think I may have found a major bug to your latest mplayer.dll.
When playing back a mms:// source the frame duration seems to double whereas the audio plays back in regular speed. Means: Video is at half speed, audio is at full speed.
Here is a debug log I did today:

Funny enough that worked in the previous mplayer.dll as for example in the T3CH build of 2007-02-16 (the then "official" mplayer.dll not your version).
As my project XBMC-TV is using a lot of mms:// sources this is kind of a problem as our "customers" will have a decreased viewing comfort when going for the latest mplayer.dll. Could you plz be so kind and look into that?
If you need any further information feel free to contact me.
Cheers
