cvs log question

[BoD]

Hi!

I'm trying to use the cvs log option to get a list of changes made to 
the files on a specific branch.

So I checked out my project on the branch and then I used this command :

cvs log -rmybranch -S > log.txt

Unfortunately the result file also contains the files that don't exist 
on the branch. Is there a way to exclude them, and get only those files 
on the specified branch?

Thank you very much for your help.
