Episode I have an EX flag?? - DVDfile.com forum for DVD, Blu-Ray, and HD-DVD

chummy34 · 12-26-2001, 08:39 PM

I got Episode I for Christmas. It's coded with EX yet my reciever (Yamaha rx-v1200) fails to recognize it. This is the first movie that I watched in DD EX. I know my setup is correct so I'm figuring the DVD does not have the EX flag. Can anyone verify this? Thanks.

I believe it does. I took a quick look at the specs on your receiver at the Yamaha website and I didn't see any references to THX Surround EX or Dolby Digital EX, but I *did* see references to dts, dts-es, Neo 6, and dts-es matrix 6.1 as well as Dolby Digital 6.1, which DD EX is not.

So, maybe your receiver does NOT have a DD EX decoder, but the dts-es decoders instead?

Peace.....

Yep, its most certainly Dolby Digital 5.1 EX!

Wow, OK... So, Dolby Digital Matrix 6.1 (which my reciever has according to the instruction booklet) is not the same as DD EX? How big of a problem is this? Somebody please take some time to explain these issues to me. Thank you.

Well, that's the big question. If the manual does NOT refer to DD EX as DD EX, I don't know if THEY call it DD Matrix 6.1 or if they are referring to something else.

Can you call their customer service and ask someone if DD Matrix 6.1 = DD EX?

Peace......

OK, I called a local home theater store that I know and trust and they told me that "Dolby Digital Matrix 6.1" simply extracts a rear center signal from the existing left and right surround speakers and that it is different than Dolby EX. Then I called Yamaha customer support and was told that Dolby Digital Matrix 6.1 is in fact the exact same thing as Dolby Digital EX but that due to different licensing issues it has been called something different. I don't know what to think. Please help.

That is exactly right. Although it is not truly a 6.1 channel format, most products will call it that to emphasize that it extracts a "6th" channel for center surround. Matrix means that the signal is encoded in the other channels, like pro-logic is a 4 channel matrix from 2.0 channels. As to the "flag", I dunno. is there a way to manually engage it? I have a home brew system and it's automatically extracted. It even extracts it from pro-logic 2 on occasion.

That makes sense. Yea, I can engage it myself (for EX discs or any DD 5.1 source) and thats what I've been doing. So the "THX EX decoders" and "DD EX decoders" do the exact same thing? Everything makes sense except the fact that it doesn't engage itself.

Great detective work!!!! It would be a bummer if your receiver just doesn't engage DD EX automagically....

THX Surround EX and DD EX are the same thing. THX Surround EX is based on DD....

Peace.....

Well, just to make sure I'd like to rent another movie that definately has DD EX w/ the flag to test it again. Any suggestions?? Eveything else with my reciever is working perfectly and I'm almost 100% sure that its just a freak situation.
