i'm sorry but not too familiar with the program.... i don't know how to identify what format is my windows movie maker and if i open the file with winamp, file is there but no time duration. so when i click play nothing opens in winamp video. this is what i did in my movie maker.. i import pictures and audio to make it a play like movie and when i save it.. a movie maker file icon is saved... i want to send it through e-mail but the file is not recognized ...how is that..
