Hi, I downloaded Knoppix 4.0.2 ISO image and burnt a CD and am using it now. Can anyone tell me what the difference is between the contents of this Live CD that I am using and the Knoppix 4.0.2 Live DVD that is sold from the vendors? From what I read, it looks like both of them have all the similar sort of programs bundled with the GNU/Linux OS. The only difference I am guessing is that files are more compressed in the CD-ROM than on the DVD. Am I right? If so, I would imagine that running from a Knoppix Live DVD would be faster than running from a CD-ROM (since it would take less time in decompressing the files from the DVD for them to be run on RAM). Is that correct?
