I've dropped them an email.

More importantly, if we were to try and use 
consumer protection laws to get a title taken off 
the shelves, then the relevant enforcement body 
would want to know exactly WHY the disk could not 
be called a "DVD". Just waving hands in air and 
saying "it won't play" isn't good enough if there 
is a reply available along the lines of "most 
players cope - why can't it be your player at 

I had a quick search yesterday. Phillips have a 
verification suite - it costs 500 for a licence 
(ouch) and I didn't go as far as looking into 
what that allows you to use it for or wether it 
includes any upgrades.

I also found this FAQ from Sonic :
It says :

The only hints I found suggest that it's only 
available to DVD licensees, and it costs a mind 
boggling amount. So I guess that unless someone 
knows someone with it that is prepared to use it 
(a bit like asking a turkey to vote for 
Christmas) then that's not available to us.

Indeed, and it's also rather borderline for discussion on this list.
