I do think the fact that it will appear on the DVD, and is using the correct casting, lends some credibility to making it canon. I would be interesed to know who the writer(s) of the short are, as that might add even more credibility. Although, it ultimately will come down to the discretion of A & E, since that will be the only real measure that we can apply.

but, just to take the other side, we've had some deleted scenes (some rather good deleted scenes I might add) that were released on the DVD, and these scenes are not (so far as I know) canon. So just appearing on the DVD is not a valid determination for the canonicity of the material. Actually, all scenes on the DVD are either canon, or something along the lines of "I think they are, but I would have to check them again" via Adam. It is my belief that all scenes they put on the DVD are intended to be canon, at least as of the time they put them on the DVD. Now obviously, they may decide to do something in a later episode that may contridict something in an earlier deleted scene, but they have sort of done this with things on the show already (retconning is unfortunatly just part of a serialized thing), so obviously we would just say the later episode equals the more correct canon, except when Adam or someone else on the writing team admits a mistake was made (like Baby Alex's appearance in 407).
