lightscribe software on 64amd risky to install

I am a recent Windows convert, & been under a rock when it comes to the linux world. Therefore I am in the bottom of the bottom 99% of the knowledge base.
 I attempted to follow instructions on Community Ubuntu lightscribe page. First, I followed the link to the lightscribe website, & then to the section for linux users. On their site, you can download either in .rpm or .deb format. When I attempted to download & open with Software Center, I got a "wrong architecture i386" message. When I went back to the Ubuntu Community page, I glanced at what they had about a "force install" & that it could break up my Ubuntu installation. * Don't want to risk that, just got up & running after tripping up after a 11.04 install, getting small problems one after another, then failing to boot & getting stumped with grub menu for 2 weeks & finally purging everything & (somehow) reinstalling 10.10, which I think worked fantastic to begin with, but that's a side issue.

In a nutshell: What I would like to see pulled off...either something compatible with lighscribe DVD drives, or simpler support, or just an update (for 10.10 & above) for the Community Ubuntu Documentation, with a "safer" way to make it work .
