Have not been on this part of the forum for while, in fact since I bought my Sony 1080 and have been very happy with it. Anyway the other day I watched Harry Potter and the Chamber, the film is in Dolby Digital EX and my amp (always set in auto) automatically switched to Ex decoding. It Does not do it on Star Wars TPM. I know that DTS was flagged but I did not know that the EX flag had been sorted. Sorry if this has been mentioned before.
