I am hoping someone will be able to answer my question...I have seen the same question posted in 2 previous threads with no responses. I cannot play downloadd video files in my quicktime or real one players...i continue getting an error message as follows...couldnt open the file----because it is not a file that quicktime understands. the files are avi however and quicktime is supposedly capable of handling these. I am running a small 2003 640 MB ibook with macOSX, and have no other problems with gnutella network....if anyone could answer this i would be grateful
