PS3 and 360 multimedia capabilities - What files can they play?

Did they change the 360's ability to use external HDD's, because I swore I read in many different places that it couldn't use them? It is a good thing if it can, since that is the easiest way for most people to watch their stuff. Can it copy files directly from an external drive to the internal drive?

I have encountered some Divx files that the PS3 couldn't play.

 Most likley from an unsupported audio codec in the file. Those are the only files that the PS3 won't even try to play that I've encountered. Even then, the PS3 recognizes that there is a DivX format in the file. It's DivX certified, so the codec is fully supported. Doesn't mean that all DivX files will be supported as there are factors like the audio or a badly encoded file.
