Alright guys. I think I have this figured out, but I want to make sure. I'd like to make backups of my HD DVD's onto dual-layer DVD-R by copying the HDDVD_TS folder, but which files do I remove to make the movie fit onto the disc? Obviously, just the movie itself will fit, and I've already removed the ADV_OBJ folder, but I'm unsure which files to remove in the video folder. Any help would be greatly appreciated. I don't want to guess and start wasting dual-layer DVD's.
