The above answers are all correct - almost any type of writable DVD will work with almost any new drive. Depending on what you want to do, though, there may be other considerations - for example, if you want to be sure your DVDs will play in old DVD players, it might be necessary to get DVD+R/RW media so you can set the book type to DVD-ROM. As far as I know, '-' media doesn't have that capability.
You can also get dual-layer DVDs that hold 8.5 GB as opposed to the 4.7 GB of a single-layer DVD, but they generally cost quite a bit more than single-layer DVDs.
In addition to that, media from some manufacturers are more reliable than others. I've never had issues with Taiyo Yuden and Verbatim media, whereas cheap store brands are less likely to be error-free and readable across many different drives.
I've never tried Lightscribe media myself, so I can't really comment on that, but they tend to be more expensive than regular blank DVDs as well.
