Uncooked

Ok so after I use "read" I get two files the .iso which is 4 - 7 gigs etc... as well as a .mds which is small "kbs" all your saying is to use that little .mds file ? Even if I click on the .iso the program says "you have selected the wrong file blah blah I will change it this time but don't do it again. So by using that .mds file all will be good ? Thanks alot ! Finally getting to the bottom of this

Ok I understand the Read mode and creating a image. Now the image is saved onto my hard drive. Now lets say i want to burn it onto my DL disk. Is it as simple as opening ImgBurn and selecting "write image file to disk" This will not select the proper layer change / the same one that was on the original disk ?

I have been searching for the last hour to find a definitive answer and couldn't so I thought I would ask. If I'm wanting to do a complete un-altered copy of a DVD using Imgburn am I better off creating an ISO image and burning to a DL disk OR... ripping the dvd to hard drive "video_ts" and using build mode. The whole picking my layer change / seamless or not is new to me and confusing. IMO I would think the ISO route is the best way ? Does it use the disks original layer change since I am not asked by the program ? I really appreciate any input on this as I am quite confused which route I should be taking. advantages / disadvantages of both etc..... Thanks again guys ! Kyle
