ive seen a dvd ram on pricewatch.com for about 300 i believe , dont know if it was internal or external though but it was for the computer .. im not sure of you need a special authoring program to burn to dvd ram like you do with dvd-r .. i wish i knew more for you..
ps.. a single-layer DVD holds 4.7 billion bytes (G bytes), not 4.7 gigabytes (GB). It only holds 4.38 gigabytes. Likewise, a double-sided, dual-layer DVD holds only 15.90 gigabytes, which is 17 billion bytes.
