DVD Controls and NitoTV

I cant get the DVD controls to work playing back an .ISO. I have updated with “smart installer” 10.4.9 combo pack, and still not working properly. Is this a keymap issue? DVD framework issue? I have read the NITO WIKI, but still confused. I have hundreds of movies Ripped to .ISO, so redoing them is…not an option. I also am having trouble playing back WMV files over the network, they work, but are choppy.

thanks!
