The version comparison rules as defined by PMS work such that 20070226 > 3.3.1, so it's supposed to behave as an upgrade if we're following the rules.

You are absolutely right. Sorry for this.
I don't think that the ffmpeg is the same. For me there are no USE changes involved.
Post the output of `emerge -pv media-video/libav virtual/ffmpeg` so we can easily compare the USE settings of both packages.

I have chromium-11* installed which directly depends on media-video/ffmpeg and thus the dependency resolution of portage works like charm. Sorry for this report.
