DVD Decrypter and DVD Shrink need Nero engine being present to burn, else they don't do a thing.
Seeing your log it's obvious that you don't use pro-DVD in combo with Burnatonce. With the old BAO versions (like the one you use) you will be able to burn DVD's only on a few Pioneer drives and -R media only. For full functionality you need the latest BAO version, and a pro-DVD binary with a licence (licence is free and the way to get it has been described many times here).
The revolution cannot be a lever, or an essay, or tablaeu, or embroidery. It cannot proceed mellowly, piece-by-piece, gently, devoutly, simply and humbly.
