Question for how to burn dual layer DVD+R with single large file

[Yasushi Okubo]

Hi experts

I am testing a new pioneer dual layer dvd writable drive with kernel 
2.6.9.5.xx and trying to write a single file (tar/gz file) that  is  
over  5G.   And I see the following errors:
It seems there is a limit on the file size. I have searched google,but I 
have not found any answer for this. 
Could someone advise me how I can get around this problem ?  I could 
burn with nerolinux indeed, but I would like to know if I can do this 
without costing me.
I am passing the filename and values to growisofs (frontend of mkisofs), 
but see errors.  I think I have the latest dvd+rw tools. 
So, does mkisofs still have a file size limit ?
Does anyone know support plan or enhancement plan of mkisofs for daul 
layer dvd ?

Thanks,
yasushi
