I just started using PRE 11. My last Adobe experience was PRE 4. I just finished a project and decided to burn to folder, both for AVCHD and DVD since not all of my family can handle AVCHD. The AVCHD burn went fine. I just burned the BDMV folder to a DVD and it played fine on my blu-ray player. Then. as I have always done for years, to make the DVD, I burned the video_ts folder to the DVD. That would not play. So then I burned the openDVD and the video_ts folders to the DVD and that wouldn't play either. I then burned directly to the disk, instead of the folder and that played fine. I could copy that DVD, and I also made an image file of it and made more copies. So, what did I do wrong with the folder approach?
