can't play the video: no suitable decompressor could be found

when I play the doa nude video i get a message like the one on the top. I tried downloading a converter to mpeg but it cant convert it to mpeg at all. Are converters only able to change the AVI if the file size is small?(that is what I thought, for I tested it on a small file size AVI and I was able to convert it.)Or is my AVI to MPEG converter smellier than sh**? Can someone help me solve this decompressor thing?
