I am an extremem beginner at making dvd copies and currently have dvd shrink and burnatonce, and I cant get it to work so gave up for awhile. I am extremely happy I found this sight. I have a couple of questions. Is burnatonce a good program to transfer dvds to dvdr's? I have read that most people think Nero is the best. And if I decide to get Nero do I have to uninstall burnatonce along with the DVD Copying CD software that came with my HP? And what is the difference between iso and video_ts? I would greatly appreciate any help. Thanks in adavance. Hopefully I will become more of an expert in this subject in a couple of weeks.
