Strange query here... merry chrimbo btw. I have a Onkyo 898 amp... and a Pioneer 2950 LD player.. I have noticed with about 3 of my DTS Ld's the amp is not locking onto the DTS signal.. and I get complete silence. I have about 25 DTS Ld's in total.. and If I play one of the ones I know work.. once the amp is locked on I can stop the player and switch discs (to one of the problem discs) and then play it fine.. The onkyo manual mentions that some discs may not work if the signal has been adjusted or altered? It may have something to do with the optical lead being fed through my demodulator before being converted to a co-ax signal to the amp. Just wondered if anyone had come across this sort of thing before ? Never had any probs with any DVD's... Cheers Matt P.S Toy story does sound great in DTS!
