Wow, Sajjad From Iran !!! Thank you so much! It works, your golden tip! Im now able to complete my music video, check out www.storung.net soon.
IRAN rules!! HA HA
Thanks for your clarification. Mine did not work either when I installed ffdshow. I was not seeing the checkbox for ffdshow in Tools->Options. I followed your steps and now it shows up in the list.
However, I still can only hear the audio from my AVI files and cannot see the video. Are you now able to use the video from your AVI files?
BTW: No-one seems to be telling anyone else what version of WMM they are using or operating systems and such, which is leading to a lot of confusion since the original posting seems to work for some and not others. I am using version 6.0.6000 on Vista Home Premium with Service Pack 1. Is that what you were using?
Thanks for getting me part of the way there. Now I just need that last little tip to get the video showing up since I do not want to have to upgrade to Vista SP2 and install a crapload of updates to run WMM 2.1 on my machine.
