I just got a new laptop and it runs Vista Home Premium. I have DVD shrink and Nero on my laptop now. I've never burned a DVD before, but my cousin does and he tried to show me how, and it wouldn't work. I was getting a message that said my DVD didn't have enough room. I saw an earlier posting about something similar and a solution: You won't notice the compression if you set your target size to 4350 as laddyboy suggested. I have my target size set at 4400 and my ISO files come out to about 4.29 GB in size. I haven't had any problems with this setting. But this doesn't work for me. When I look at my blank DVD in my computer, it says only 4.07 of 4.37 GB free. And of course the DVD says 4.7 on it. Does this make sense to anyone?
