OK, if I have say either a (DVDR) disc <2Gb, or an image of same, and attempt to make a recording using 2 writers simultaneously, the disc will write OK up to the lead out, where one (whichever burned the faster) will then burn the lead-out OK, but the other one, which will only write the lead-out once the first is finished, will make the leadout of the disc last right to the end, so the whole disc is written on.
Both discs come out completely readable, but if you're writing at 2x obviously this can be annoying as it takes a while to complete Anyone else getting this?
