The two main programs that would help are...

mkisofs - for creating the filsystem layout

cdrecord - for writing to a disk[/quote]

i have some puzzle about the burn used the command:
1. do i need erase the old date on the DVD-R/W disk first?
2. do i need format the DVD-disk again?
3. I am very sad beacuse i can not find the "mkisofs" and "cdrecord" command in my system, anywhere can download these 2 package?
