Hello Roger and all...

In these cases most often the center hole is punched in the wrong place.  If 
you have the disc, this can be fixed by slightly reaming out the hole and then 
centering the groove spiral on the disc before transferring it.

CEDAR has a process called ReSpeed that can do just that... take an off center 
transfer made from a disc and correct it without the necessity of having the 
original disc to do it with!

I've used it to fix an otherwise previously impossible problem where the disc 
grooves were oblate, that is, football shaped probably caused by improperly 
removing the disc from the record press in the pressing process.
