Weird font being used in player

For a while now, in my Flash player embedded in my browser (any browser I use),

a weird font shows up for some of the text. 
http://www.daybreakmedia.com/images/font_issue.jpg, taken in Firefox (you can 
see the font in the band name at top and on the song titles):

 This also occurs in some PDF documents.

 I've tried a bunch of things, including reinstalling my Flash player and the 
like. Nothing has worked. I'm going to assume it's an Adobe font issue, but I 
don't want to go into the font file and muck something up just yet. Plus I have

no idea what I'm looking for.

 I'm running Mac 10.4.11 and Flash Player 9.

 Any ideas or leads? Thanks.
