Converting .dvdmedia to .m4v

Just wanted to see if anyone has had success in finding video conversion (specifically .dvdmedia to .m4v or mp4) freeware that does not have a watermark? I have tried a numer of 'free trails' but they have all been about as 'free' as Hester Prynne walking around with a big, red A. I have a couple programs that run conversions great, but that '.dvdmedia' extension is throwing them all for a loop.

Please let me know what y'all have seen and use. Thanks
