There are 2 types of dvd media, single layer and dual layer. dvd's you purchase are 9.4gb dual layer. current dvd burners are 4.7gb single layer, current dual burners are only 8.5gb. (The explanation I was givin is that they don't want us to make 1-to-1 dvd copies, that's why dual layer burners can only burn 8.5gb. I'm hoping this will change very soon)
I just got done doing the research, and I've narrowed it down to a few options:
8x/12x DVD+R: Most popular brands can do either 8x +R or 12x +R (notice 12x -R is currently not possible) If you don't care about dual layer, get a 12x +R burner, they aren't too much more than the 8x's. On the other hand, if your short on cash, 8x will do just fine.
2.4x DVD-DL: I couldn't find a brand in my price range that could do both 12x +R and dual layer. So it's currently one or the other. 2.4x dual layer will be slow (up to an hour to burn) And media is currently really expensive and scarce, but if you want the capability to burn dual layer, this is it.
Wait: We're right on the brink of an upgrade in options. Before January (as early as october/november) we'll see 16x dvd burners, as well as 4x or higher dual layer burners. dual layer and faster media should also keep dropping in price.
With that said I just got done buying a Lite-on Dvd burner. It does 12x DVD+R 8x DVD-R and 4x DVD+-RW. It's only $85 shipped through newegg.com. Lite-on is a cheaper brand, but I've had good luck with my Lite-on dvd and cd-rw, so I'm sticking with it. NEC is also a very popular brand. Plextor is one of the best optical brands, but obviously you pay for that. If I had the extra money to burn, I might buy one. 8mb cache would be nice, but it's just an extra feature, not neccesarily needed.
Anything I miss?
