Thanks for the info Brad, yes that does help.
I would suggest not using the MyDVD Express program and stick to the MyDVD program instead.
There you can break the "Burn" into 2 phases to help isolate the problem.
When you click Burn, choose Save Disc Image File(iso file) instead of the burner. Write down the location and name, you will need it later.
Assuming all goes well close MyDVD and open Video Copy & Convert. Point it to the iso file and let it burn.
Let us know how this works out. Assuming it does I have another tip or 2 you will like.
(if it doesn't work, those tips wouldn't do you any good
