Hi Carl, Thank you so much for the find out! It works now! As this might be indeed a bug in mplayer, hope the next version can have it fixed. One thing I notice that the trick only works for the latest build of mplayer, but not for the mplayer shipped with smplayer. Anyway, time to upgrade. The reason I used zip file is to avoid potential confusion of file corruption during upload/download. I am a bit old fashioned, maybe I should have made an md5 file too? lol Thanks again!

Why did you zip the file? Carl Eugen
