I can't recall where I read the blurb about which (dual/double layers) DL's the 100 would write vs the 109. Nor could I vouch for it's accuracy even if I had read it. But, I agree that anybody that needed a DVD writer did the right thing by buying the DVR-109 for about $50. My own systems show a steady progress from the DVR-103 to the -109, and no doubt others will follow. --Steve At 9:55 PM -0700 6/1/05, Robert Meadors wrote: >Steve only wrote about compatibility not speed.
