Ok so for years I have copied "movie only" of my favorite movies in the file folder manner. (folder with ts_video and ts_audio). and used nero to burn it to dvd. I started to play around tonight, and copied one in the iso image, and burned it in nero under the "udf dvd" setting. ... my question is the final outcoming dvd looks EXACTLY the same as the old way I did it to my unprofessional eye..- - is there any advantage or disadvantage to copying the file in iso instead of the ts_video/ts_audio folders? FYI I use anydvd/clonedvd for ripping, and nero7 for burning.. Thank you.
