Hey All, Both these questions have probably been answered many times but I was wondering if anyone knew why we need to compress the DVD (shrink), to put it on the disc? Isn't the disc I have as big as the disc they have ? and if not , Why? Are their disc Double layer? I know that since I have been buying DVD-r, +R, etc. I have not come across any that are silver on the burning side. Are these special for comercial use only. Still they should be available SOMEWHERE. These are some questions that are bugging me. Any answers would be appreciated greatly.
