Well, I have to correct myself. My test VIDEO_TS folder must have a problem.
I SWEAR I watched the original video and converted it to ISO with CloneDVD with absolutely no problems. I ran the batch ImgBurn, watched the ISO, and saw a skip 3/4 through it. I suspected the speed issue, boosted some buffer settings in ImgBurn, and tried again. This time, I saw a skip in the first minute. I again watched the ISO made from CloneDVD with no skips. Convinced ImgBurn was presenting a problem, I cleared out my test folders, including the good CloneDVD ISO.
However, I just hit the same skip from the VIDEO_TS folder. I SWEAR though that it wasn't there earlier... Can moving or copying a VIDEO_TS folder in Windows introduce skips? I may have had more than one copy of this VIDEO_TS folder...maybe I kept a bad one. Hrrm...confused...
Going back to my original thought/concern...should I have any concerns about ImgBurn going too fast on my aged PC and introducing an error while putting the video into an ISO container?
