Historically, I've checked the quality of arXiv output by reading the PDF it creates; I learned today that this actually a serious mistake.  If you look at the [PDF](http://arxiv.org/pdf/1001.2020.pdf) and [DVI](http://arxiv.org/dvi/1001.2020) for my most recent article, you'll see that the PDF looks fine, and the DVI is essentially unusable from a mathematical perspective.  The tikz pictures don't come out at all, and there seem to be serious font issues.

I'll note that this file compiles fine as a DVI on my home computer.

>What's causing this?  Is it a problem a user can fix by include font/style files with his/her upload?  is there someone at the arXiv I should be telling to install something?  Why is the arXiv less competent than a home installation of MikTeX?
