I have to "save As" ,then play them from my home with VLC . That sounds like you're dealing with attached files which aren't properly identified. When emails are properly created, the client mail program will put headers with the attachments that say what type of file has been attached (e.g. video/mpeg), and the receiving mail client will use that information to pass the file onto the right program when you try to open it (*your* computer's configuration will determine what's *your* program to handle that type of file). When emails are badly created, the mail client doesn't identify the contents its attaching, either giving a generic binary/octet-stream description, or even a wrong one (e.g. text/plain). The mail client receiving such bad messages will either have to guess at what to do, or simply leave you to save the file and deal with it yourself. Have a look at the message source, and see what headers are there just above the attachment section. I've placed an example of an attachment header, below. It's the content-type header that describes it. > --Apple-Mail-6-996041395 > Content-Transfer-Encoding: base64 > Content-Type: application/pdf; x-mac-type=50444620; x-unix-mode=0644; x-mac-creator=4341524F; name=Tim BizCard.pdf > Content-Disposition: inline; filename="Tim BizCard.pdf" > > JVBERi0xLjQNJeLjz9MNCjM1IDAgb2JqDTw8L0xpbmVhcml6ZWQgMS9MIDEwMTA0My9PIDM3L0Ug > NzY5MjEvTiAxL1QgMTAwMj -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
