Sure. As long as the file size is not over the Gmail limit (which I think is pretty big)
Instead of email you might want to go to www.dropbox.com
and set up a free 2GB account. Then grab a copy of Dropbox out of the repos. After setting it up 'dropbox' will be a folder in your home folder (you can specify another location if you want). Copy files to it and then set up Dropbox on your other machine and you will have access to the files. Its easy peasy and faster than adding an attachment to an email waiting for it to upload, waiting for it to get scanned and work its way through the email servers. I use dropbox for all my inter-machine file movement now.
I did exactly what you are asking. I downloaded some AVI files and then opened them on another machine that has a burner and made my DVDs
