The big tooth little tooth scenario is very common on a crosscut saw. However, it's not typical on a dovetail saw as those teeth are typically filed straight across and not subject to that issue. If this is a new saw and just purchased, I would send it back to Veritas for rework. If it's used, then who knows what might have happened to it since it left the factory. Filing a saw like this in rip profile is not hard.

PS. If you have an iphone, take a close up of the teeth from the side and post it here. The macro feature is very good for this sort of thing.
