hi guys, another factor, which i didn't think could be the reason, may cause all these headaches: enclosure. i put the burner inside of a 1394 enclosure. this is my thinking, if it were the enclosure, neither would i be able to burn -R and +RW disks. silly me wanted to make things simple, but didn't realize i didn't provide enoug information.
a friend of mine says he had similar problems, he has a burner same as mine, and we successfully burnt one disk using his desktop. i will go to his home again tomorrow to see if my burner works in his desktop.
i noticed one big difference though. when burning using the desktop, at the final stage, DVD Decrypter would say how many percentages finalizing the disk, for example, 11%->23%->47%...till 100%. never have i seen that when using the enclosure, and that's why all the disks are incomplete.
back home, i searched the forum, and found a whole bunch of posts dealing with enclosures. do you guys have a quick answer to my problem? or could you please give me the link to the post that i should read? thanks.
