I don't think they'll fix anything, not sure what they could do other than prompt a full download when you insert the disc, which would probably piss off a lot of people.
I've arranged to exchange my disc where I bought it, but it's an online shop so it'll take a while. And it'll probably be a lottery to get one that works... yay.
Sony support acknowledged the issue and told me to get the disc exchanged where I bought it.
Shit happens, this is the first time I've ever had any CD/DVD/Blu-Ray that didn't work.
