Sorry for the basic questions, but I'm pretty new at this. I'm currently at v23. Can I upgrade straight to v26? If I can, will it include any updates for the versions in between?

I just burned the disc with Alcohol 120, but the only option I had to change it to was 48x from maximum. I have a Sony DVD burner to do both DVD's and CD's. Do you think that will be a problem? Thanks.
