I was failed to convert a rmvb file to VCD by Winavi Converter. I always get this message " Unable to source file " What does it mean? Hoe can i solve this problem? Thanks

you have to move the file into a directory that does not contain any charactor that winavi does not recongize, like a chinese charactor. in addition, you have to change the name of the file by removing any un-recongize charactor. I usually change the file name to a number. this should do the trick.
