Yep, that's one option.
But you've got others.
I think DVD-Rebuilder is still free and it works with CCE.
Please be advised that AutoQ3 and the URL you mentioned in your message are from an individual known as Avalon/Amnon/Amnon82.
Try to make a search by Avalon in here and you will find very interesting stuff about him.
If I were you I would never use anything coming from him because it might actually be somebody elses' work and not his as he advertises.
Have you tried CQMatiq with TMPGEnc?
They can easily pull the trick.
Or DVDREasy that can also work with either CCE or HCEnc
.
Hope I was helpful.
Cheers
EDIT: I just noticed you were talking about CCE
2.70.
I don't know if any of the above mentioned tools works with CCE. 2.70 but you might want to give it a try anyways.
