.ogm converter

[linkmaster6]

I'm trying to find a free .ogm converter so i can convert some .ogm files into a type that will work on most DVD players. if you know of where to get one it would be greatly appreciated. So far I have downloaded one from AVS media, but when I convert it to .avi it leaves a watermark on it, a pop up appears periodically on the video stating that it was converted by AVS. I'd like to get a free one that doesn't do this
