[newby question] what are the differences among dvd-r, dvd+r, dvd+- burners?

[phatxtiger]

dvd-r, dvd+r, dvd+- burners and blank medias.

How are they different? and what are dual layer burners?

I am trying to get a burner under $100 but don't know what I should get.

Please help thx.

they're just different formats of DVD's. more here: http://www.answerbag.com/q_view.php/2279

dual layer burnneres can burn on dual layer discs which in short means twice as much storage (8GB) per disk.

if you can find one under $100, then go for a DVD+R. media is cheaper.
