I installed the DVR-111D on my 733 MHz Quicksilver Mac running OS X v. 10.3.9 with no problem. It has no problem reading CD's which I burnt using the cd burner which came with the computer. what id does not do is recognize blank cd's so I now can not burn cd's. I get the error message as follows - "The disc could not be used because the disc drive is not supported. (Error code 0x80020025)" davis a. gaffga • photographer 7 koral drive p.o. box 750 southampton, ny 11969-0750 phone & fax : 631-283-9010 www.davisgaffga.com -------------- next part -------------- A non-text attachment was scrubbed...
