convert vob files for use in FCP X

I need to convert VOB files for use in FCP X on my macbookpro in OS X Lion (10.7.5) I use Clipwrap to convert other formats, but it does not seem to accept VOB for conversion (or if it does, I have not figured out how). In searching the web, I've come across several products that tout themselves as the best, fastest, easiest VOB to Prores converters etc., some that advertise as "free" when actually only a watermarked trial version is free. I have no idea of the actual quality of any of these (some examples are Brorsoft video converter for Mac, and Acrok HD Video Converter...), and would like some input from folks w/ experience in these things before dropping $ on the problem.

In another thread on this site I read something about MPEG Streamclip, & something about needing to separately download an MPG2 converter for it w/ Lion or Mountain Lion - the process sounded confusing and I couldn't tell if it applied to my situation or not...

Thanks in advance for any light anyone can shed.
