I'm SO NEW with these rippers etc... I've tried to read all the possible guides, forums and glossary and I just can't find the answers so.. I ripped a DVD to my hard drive by DVD Decrypter (in order to burn it to CD/DVD) and it created 3 files with extensions .I00 , .I01 and .MDS . What are these? The guide says I should burn a file with an extension .DVD but it doesn't exist! Is there something that I don't understand or do wrong? Then another stupid? question.. do I have to burn the movie with DVD Decrypter or can I just use for example Nero 6 instead? Which one do I need to choose and why: DVD-Video/VCD/SVCD?
