I have bought on LDDB, but it's the el-cheapo lots and bargains on ebay that always drag me back in.
I'd get them (Brosnans) anyway. Pretty cheap too. The surround downmix on Goldeneye is outstanding.
If anybody has a reciever that can do Dolby EX and has the SE disc then if the track is flagged as EX we know for sure. But I doubt it to be honest.
