My elderly grandfather recently bought a Sony Bravia tv/dvd/blu-ray all-in-one job and it won't play certain dvds, coming up with text on a black screen such as "prohibited functions" or words like that. This is in London, England, the dvds in question are definitely region 2 and work on other, more simple, dvd players and is causing him great concern considering the cash already parted with. What gives guys?
