Old post, I know - but I had a similar problem and found a solution. I 
found this message in my mail archive when searching for a solution.

You need to specify to babel that you are using greek.

IE - in my case, I added this to the preamble:

Things worked perfectly.
Also note I added the psgreek package (not part of TeXLive but on CTAN)

Anyway, I'm guessing you have found a solution you like, but since I did 
not see the babel solution on the list, I thought I'd reply so it's there.
