I have educational DVD (not movies) that contain videos, navigating instructions, several chapters,etc. I need to access these DVD's while on the road since I don't have space to bring all the dvd's. All the software for dvd ripping, at least the ones I read, are for copying dvd movies into the HD. I tried already several but did not work for my educational DVD's. Is there a software that can copy the exact DVD content and not just a software for copying DVD movies? When I tried the dvd ripping softwares and click on the open file, nothing comes out on the "file to copy" even though what is written on the lower case box is "all files" . Please help. I have way too much HD space and I don't want to be bringing expensive dvd educational materials. Thank you very much.
