"Toast could not detect the format ....." Why is that?

[Ivor Bigone]

I have a ISO file that when I try to burn to DVD (Copy/Image file) I get the following messages.

"Toast could not detect the format of "xxxxx" PAL.iso .... click continue if you are certain"

When I click continue I get
"CD-ROM XA Audio tracks cannot be written to DVD"

I have used toast for many years but just updated to 10.0.9. Is this relevant? I am running Mac OSX 10.6.8. What's my problem please. Can it be corrected?

What does the iso contain?

It could be a vcd or svcd and those can't be burned directly on a dvd. See http://forums.support.roxio.com/topic/16359-audio-error/ .

I don't have any more info other than it is a ISO movie image file at 4.7gb. I have checked the link to gave me and see this ....

"If you want to burn this movie as DVD-Video, then you'll need to extract MPEG files out of the disc image and transcode them to DVD-Video."

I don't know what this means but would it help?

After some investigation I suspect that this is a Wii games file not a movie file as I understood.
