Burn a 4.2 GB file to DVD

I want to burn a 4.2GB file to a dvd on my Mac (OSX 10.5). I know I can split the file into smaller pieces, but I prefer to keep it as one file. I don't mind that I cannot use Joliet or ISO 9660. The dvd should be accessible from Linux or OSX afterwards.

do you have a dual layer DVD burner?  the DVD-DL holds 8.6 gig
I think the problem is more the size of the individual file. a single layer dvd holds 4.7gb i think. Using the DVD-UDF format would remove the 2GB limit and I am certain that it is readable from linux, not sure about OSX. As to how to do this, it would depend on your software but there should be an option somewhere in the burning process for this.

"... a single layer dvd holds 4.7gb i think ..." ==>  No, it actually holds 4.38 GB

This is the classic "computerese" vs. "disk-driver-maker-ese" difference in measurement units.     A DVD will hold 4,700,000,000 bytes ... but in "computerese" that's (4,700,000,000)/(1024 * 1024 * 1024) = 4.38GB     [To be precise, a DVD+R holds 4,700,372,992 bytes = 4.378GB   and a DVD-R holds 4,707,319,808 bytes = 4.384GB]

But to answer the question, you can easily write a 4.2GB file to a DVD.    You simply have to write it using UDF format, as noted above.    As long as it's smaller than the capacities I just noted it will work fine.

Thanks for all your replies. I created a encrypted disc volume of 4481 mb, then used hdiutil to create an UDF iso image. You don't need Toast for this.

For hdiutil see: http://www.macosxhints.com/article.php?story=20070612161317338
The conversion by hdiutil results in a slightly larger file (1,00024*).
