Whats the difference between DVD-R 2x writeable vs. 4 x's writeable blank disc's. I can buy 25 4x's writeable at Best Buy for $1.61 per disc or 2x's writeable for $1.00 per disc. Both are 4.7 GB capacity. Is there a link that will help educate me? Thank You, Chuck Brook PS. I got a Panasonic DVD Recorder with 80 GB hard disc for christmas and am still learning. It's a steep learning curve. I just finished hooking it up to my Sat. reciever(dish 508 pvr), an A/V receiver and a VCR and a sony 36" wega. What a job that was.
