I don't think there's any difference with the burnable part of the discs between silvertop/injket printable/LightScribe - it's more dependant on the manufacturer and batch (Mitsubishi outsources their media production to other companies, but they all use Mitsubishi dyes.)
It shouldn't make enough of a difference to be noticeable anyway - maybe you need to investigate your burn quality rather than your disc quality?
Burning is pretty much everything, since DVDs are mostly all the same. Some are just better quality when it comes to burning. If you have a few DVDs to waste, try out different settings and burn the same game a few time. Find out which is the fastest.
just came into my head u said they lag, what speed are you burning at? try burning slower (ie 4x dont go under 4x its not needed) to see how it goes, silvertops i havent heard of are they just unbranded discs? probably very cheap dye in them and not very good discs...
