Intervideo DVD Copy - behaviour by design
This behaviour is deliberately configured by Intervideo. This program only allows you to burn the DVD or save to the HDD as an .AVI file. The program deliberately does not allow you to save the AUDIO_TS and VIDEO_TS folders and .VOBs etc to the HDD. It will only let you burn them to a DVD.
I have used InterVideo's DVDCopy Platinum more to convert to VCD rather than to make a DVD. In this function is does as well as any other DVD to VCD program. It is fairly quick on the conversion and will save the files to the HDD. The program is, of course, unable to work with CSS encrypted movies by itself.
You can also use a good undelete program or after transcoding your DVD to HDD, Intervideo is going to parse the files (takes about 4 minutes). In those 4 minutes you select all files and make them read only. when DVDCopy is done the files are ... still there
