I have over 10 games. I just checked them ALL and NONE of them got a Video_TS folder (maybe you was referring to a ''Video'' folder
Have you ever did a DVD Video backup? Even if the .vob are encrypted, you can see with an explorer all files/folders on the disc, but in somes cases, very uncommon, the Video_TS in the root doesn't show up, the directory is ''hidden''. Specialized PC DVD ripping programs can do the job easily, but it seems that the DVD2Xbox ripping library is not powerfull enought - Yes DVD2xbox decrypts .VOB directly on the xbox HD - this is pretty cool - but in the case of a dvd video disc such as this one that I hold in my hands, Undergrads Season 1 DVD1, the dvd2xbox is simply useless.
There is very few informations about how ''hidden Video_TS'' works, but if you explore it, you'll just see a blank Audio_TS directory and nothing else.
DVD2xbox detects the label name but unable to grab the data, 0MBs of total copying.
