Hi guys, I have an IBook G4 running Mac OS X 10.3.9 , 800MHZ G4, 640 MB RAM. I tried to copy my 10-minute DVD from the internal drive: Mats---a CD RW CW 8123 (it's a DVD ROM as well , but I don't know why its model name didn't say that?)that came with the IBook, to an external burner: Pioneer DVD RW, DVR 106D. 1) When I used the "CD/DVD Copy" function in Roxio Toast Titanium version 6.0 to copy the dvd, after 1 minute or so, an error message appeared: The driver reported an error: Sense Key = Illegal Request Sense Code = 0x21 , 0x02 Buffer Underrun 2) I tried to burn it with only 1x speed and still didn't work. I was told may be it'll work with different brand of disks. But I know it's not the disc brand, external drive (Pioneer) nor bad media file problem, because I used the same external burner(Pioneer), same original DVD, and same brand of media DVD disc to do it in my eMac which has the same RAM, only runs OS 10.2.8 but is 1G MHZ, and it burns beautifully. 3) I tried copy the VIDEO_TS file onto my hard drive, dragged it into the Toast Titanium's video tab "DVD- Video: My DVD" window and tried to burn it. It stopped after about 3 minutes and the same message appeared. a) What's wrong with the first step? It worked on the eMac! b) Do I have to burn it slowly? I tried x1 but didn't work. c) I dragged the Video_TS file into the Data window but it became a DATA DVD and won't read by neither a regular or computer DVD player. (It'll only play if I go to Folder --> Open VIDEO_TS Folder, then nevigate it to the DVD, then it'll play. d) I was told that I could use the Disk Utility to burn and I found some info on this site: http:// forums.macosxhints.com/showt...hlight=burn+DVD. But I couldn't understand half the jargon and it didn't seem that it's sucessful anyway. If someone know how to do this right, can he/she show me a simple step-by-step? All I really want is to just copy from one DVD to another DVD and play. And if copy doesn't work, how to use the VIDEO_TS file in the desk top to burn so that a regular or computer DVD player can just insert and play. Can any intellengent individual points HIS finger and shine some light on me, PLEASE? Much thank you all in advance.
