Folks, I need some help in deciding on a DVD-R. Can someone tell me the difference between "General Purpose", "Printable" and any other types of DVD-R's that are available in the market? I need the DVD-R to record movies with my panasonic ES10 DVD recorder. Please take a look at http://www.blank-cd-cdr.com/dv4xblme.html and let me know which one is recommended! I guess I am OK with an 8X disc (not sure if it really matters when I record using a DVD recorder).
