DVD burning..

[Jeff Mitchell]

 	So far I'm having no luck so thought I'd post and ask for help :)

 	FreeBSD 5.4, BenQ DVD burner, using DVD-R media. GENERIC kernel 
with ATAPICAM added.

 	Built an iso with mkisofs, and can burn it out with burncd to CDR 
no problem (if 700MB or less or so, of course.)

 	For DVD, built a 2GB .iso using the same mkisofs command..

 	mkisofs -o foo.iso -J -R filelist*

 	'cdrecord' seems completely crippled and I'm amazed no one has 
written a 'Free' version (no dependancy on getting key files that expire, 
or reliance on one person to generate them, etc.) Took me awhile to figure 
out how to get the key files going... but it now has what seems like a 
common problem -- it starts up, does the 'grace time', then "Alarm clock" 
and it stops before doing any work. So after a few hours of buggering 
around I gave up..

 	Installed the dvd tools to get growisofs since this seemed like 
the main alternative to cdrecord. (burncd didn't seem to like to burn 
DVDs, though I forget exactly its output.)

 	growisofs seems to almost work, but breaks and is slow:

 	growisofs -dvd-compat -speed=4 -Z /dev/cd0=buckdvd.iso

 	That results in..

Executing 'builtin_dd if=buckdvd.iso of=/dev/pass0 obs=32k seek=0'
/dev/pass0: "Current Write Speed" is 4.1x1385KBps.

 	So it would seem to take hours to burn a DVD, and tanks after a 
few moments anyway.

 	Any ideas?

 	Aside .. seems like a lot of tools depend on cdrecord to work, and 
it seems cdrecord with its key situation is volitile and requires userland 
knowledge to sort out.. so a bad situation :(
