I am a newbie and have read alot of different guides on burning and dvd media. I am still not to sure which media I should purchase for my burner.I have read that princo,maxell and ritek are the best in media. Is this true? If so, where can I get the best deal? Someone told me www.egghead.com had good deals on media. Also, next to the media is 2x,4x, etc. Is this important? Thanks.
