Update problems: packages held back

When I try and upgrade I get packages that are kept back, when I use dist-upgrade they will be upgraded however I get this warning:

I don't know whether to upgrade or not, looks like it might break my video

I would not update. Especially if you currently have packages in a working condition. Never run a partial update or install packages kept-back. They are like so for a reason. Are you running Maverick BETA? If so that would explain it. You should wait for the packages to sort themselves out, and they will.

(I am actually taking a break writing a blog article that explains things like this right now, odd).
