When I boot the (non-Ubuntu) DVD from the burned ISO, it starts to install, then gives a blank screen.

Is it possible to compare the DVD to the ISO? Apparently, only if you compare an exact number of bytes??

Here's an ISO I downloaded:

$ md5sum Vicibox_v.6.0.x86_64-6.0.3.preload.iso
d676e7c90f2f716c2844a507a52686b2 Vicibox_v.6.0.x86_64-6.0.3.preload.iso

which matches http://download.vicidial.com/iso/vicibox/server/Vicibox_v.6.0.x86_64-6.0.3.md5

the burned cd seems ok:

$ cdck -t -v
Track list (1-1):
1: 00:02:00 (sec: 000000) data
170: 82:48:60 (sec: 372510) data (leadout)

Disc status: data mode 1
Multisession: 0
Audio status: failed to get, reason: Input/output error

Try to find out what sort of CD this is...
CD-ROM with iso9660 fs
iso9660: 727 MB size, label 'KIWI CD/DVD Installation '
Creating software: '0xc1c764e9'
bootable CD

NB! For disks written with some burners cdck might
report about unreadable sectors at the end of the disk.
In such cases you can just ignore those warnings.

Reading sectors 1-372510
372508 ok

CD overall:
Sectors total: 372510:
Good sectors: 372510:
Bad sectors (incl. with poor timing): 0
CD timings:
Minimal = 0 usec (0.000000s)
Maximal = 59 usec (0.000059s)
Average = 0 usec (0.000000s)

Conclusion:
Excellent disc!

When it goes to install the OS (not Ubuntu) I just get a blank screen.

How do I compare the burned DVD against the ISO?

see also:

md5 for iso checks, but burn always fails

which I'm taking a closer look at again. I'm thinking of booting the ISO from the hard drive.

-------------------------------update----------------------------------------------

dd checks out:

thufir@doge:~$ 
thufir@doge:~$ dd if=/dev/cdrom of=/tmp/Vicibox_test.iso

1490040+0 records out

thufir@doge:~$  md5sum /tmp/Vicibox_test.iso

You could just dd the DVD contents to a new ISO and compare it to the original ISO:

dd if=/dev/cdrom of=/tmp/Vicibox_test.iso
md5sum /tmp/Vicibox_test.iso

If you get the same MD5SUM then the optical drive is capable of reading the media without errors.
