DVD to DNXHD or PRO RES HELP

[thefilmaddict]

I used to use mpeg streamclip to take parts of DVDs and turn them into DNXHD files. it worked great. I could mark an in and an out and then export.

Now that I use OS Mavericks, mpeg streamclip does not work. It asks for a MPEG 2 Component. I bought it, but it wont install into Mavericks.

Any other programs that will do the job on a mac?

Thanks!
