Thanks for your responses.
“Are you sure your drive supports DVD overburning ?” No, I got the info on the Lite-on site. There’s no indication that it supports DVD overburning.
“I’d suggest you to slightly shrink the dvd image …” I don’t think that this will work since I can’t reproduce the ISO from the original source.
Answers to coolcolors:
Burner is a: Lite-on DVDRW LH-20A1L
Data to be written: 8,208 MB
space available on disk: 8,152 MB
Media: Memorex DVD+R DL 8.5 GB (part number: 3202 05647)
The image is an .ISO
Someone suggested I extract some unnneeded items from the ISO to reduce the size to within acceptable limits, then burn it.
This sounds like a workable solution; but I’m not sure how to do this. Right now, my best guess is to mount it in Alcohol 120%, extract as above, create the smaller ISO with Alcohol, then burn.
If there is a better way, please let me know.
