AFAIK, there is no technical difference between playing a side of a DVD-9 and a DVD-18. They should look identical to a player - just like the two sides of a common DVD-10 are DVD-5's
IMHO, the problems being encountered are entirely down to manufacture problems, DVD-18 discs are by far the most difficult (and expensive) to produce. Universal are not being "cheap" by using DVD-18's. They may cut down the number of discs and the packaging, but any gains are lost in the expense of producing in the first place. There are few factories set up to make 18's.
Indeed, I can imagine that in the UK there are no such facilities. Everything so far released in r1 on DVD-18's has been released here on DVD-9. I have never seen any DVD-18 here.
It may be that certain brands of player or newer players are better able to cope with inherent faults than older players.
It is even possible that cheaper or less sophiticated players will ignore things that more expensive ones won't. I've seen that happen before.
I really wish someone could put one of these discs, particularly one that is known to have caused problems, through a disc checker. There are numerous freeware checkers available.
I'm willing to bet it would show up the equivalent of CRC errors or flaws in the data layer.
I am made particularly suspiscious by conflicting reports of "good discs" and "bad discs".
