I think (as hinted at in the thread DrageMester posted) some LiteOn DVDRW drives (maybe the models introduced for 2006 through possibly 2009, maybe newer) also support TE/FE tests. How well that may work for DL media and/or with the newer drives, I do not know. I'm also not sure which versions of CD-DVD Speed support this (if any), if ODC supports it for the drives, or if you can find the requisite tool made for LiteOn drives (also mentioned in the link provided by Drage).
For your specific purpose, TE/FE might help to show if there is a problem focusing on the media or keeping track of the...err...track. There could be many other reasons for the outright failures plaguing your MBI DL burns, though, but it is a tiny step.
