It MIGHT work now…I’m not sure. It didn’t used to go up to 2 hours but if you have version 5 or 6 I think it’s possible it will work.
You’ll have to go into the prefrencs before you start working and set the encoding to “Best Quality.”
I’m afraid you may just have to use a disc to test it. That might be the only way to really know for sure. I’d suggest not spending a lot of time on the menus for the test. Just add the video, burn a disc, and see if it works. If it does, go back and make it look the way you want it too.
I’m also not positve it will take DVCPROHD files. It might, but if it doesn’t you’ll want to export from Final Cut as an anamorphic DV file and then take that into iDVD.
