If they are in the "standard" mpeg-4 format which no one uses at the moment or in quicktime format, which some use. It still won't be able to read an "windows" format file, even though it may be mpeg-4 inside. The codec is "mpeg4" but the file format (that goes around it) can be something else. Crazy, isn't it? I had thought this was finally going to be the holy grail for apple and get support for most of the (new) windows files, which are variants of mpeg-4 (divx,xvid,WMF,etc) but it still can't read the encapsulating format. Now If someone was able to make a plugin..Yeah. That wouldn't be too hard - It just needs to be "smart" enough to read the format, the built in quicktime cosec's should be able to decode the rest. thanks, Ian
