Ok, so, the bug I alluded to in the AnyDVD HD forum. This may be a known issue but I certainly haven't seen it mentioned anywhere. If I rip a DVD to an ISO image using AnyDVD + whatever(IMGBurn, CCD, etc) and then I mount it in VCD, if I then try to open it in CloneDVD Mobile or CloneDVD, the preview doesn't work. I get an error in green text about not being able to open the VOB files. Yet if I continue to process the disc, half the time I'll get decent output and other times the video's completely garbled. I'm running Vista with UAC turned off as you probably know. I don't know what other information I can provide that might be of help. (I don't have the exact error message and I've just uninstalled VCD to test out Daemon Tools.) This works fine if mounted using Daemon Tools. Same exact image that gave me an error in VCD mounted perfectly in DT and I was able to see the preview window in both CloneDVD and CloneDVD Mobile with no errors. I'm always willing to help debug issues so if you need anything from me let me know. Thanks!!
