TempDVD Folder

I've seen this folder for a while located in the root directory, but not knowing where it came from, I had not touched it. It contains two other subfolders AUDIO_TS and VIDEO_TS, as you would find on a movie DVD, so I kind of thought that it came from PowerDVD, or some other video program that I've installed, but when going to the Previous Versions tab of the folder's Properties a bit ago, it showed two dates, one from just a few minutes before checking, and one other from last week. The only videos that I have played today were on Hulu, which I doubt would need this folder, so how do I determine it's origin?

EDIT: The directory is empty of any files.

I think it might have come from a program called "AnyDVD" or "CloneDVD"? Could be DvdDecrypter?

I don't have either of the first two installed at the moment, but DVD Decrypter is. It could be the source of the folder, but I don't recall seeing it before with other installations, and I haven't actually used it since I installed it, long before the dates of the folders.
