Mater and commander has a distinct pop at around the 14 and a half minute mark, when russels talking to the doctor on the stairs. Happens everytime I play it.

I have a Samsung BD-P1400 hooked to my Onkyo 605 by HDMI cable.

Anyone else had this?

I think I will try a Yamaha service centre tomorrow. If they are unaware then will send email to Yamaha Customer support here in Australia. If there is new firwware then they should know about it.

Thanks Bryan...please keep us in the loop on what you discover. :)

As i'm sure most everyone with a Yamaha will be very interested.

I've emailed Customer service in the EU (where people on AVS say there is a fix, but I havn't heard anything back - they probably went "your not from the EU" and hit delete!

Anyone know if Species region B is "safe" from the bitstream bomb? I have friends comming to watch it tomorrow..and i'm nervous for my speakers...but i wanna watch it lossless cos they are non-believers of HD and need to be shown the quality!! In the usa its PCM no no reports i've found...but has anyone tried it?

These codecs weren't designed for bitstreaming. They were designed for in-player decoding and mixing.

A good Audio Receiver does more than decode a codec. Quite a bit more.

I get a very loud pop on Eagles Live Farewell Melb HD DVD, on track 5, on my XE1 - Yamaha 3800.

I had the disc replaced by Amazon but the second one does the same thing in exactly the same place.

Yes it is, thankfully it wasn't at supersonic levels when that happened. :blink:

It only gets to that level for Hotel California. :blush: :D

interesting, the DTS website has had bitstreaming defined as a way of enjoying dts-hd/hr/ma, using a bitstream capable player and an avr/pre-pro with suitable decoding, as far as far back as I can remember.

watched eagles a few times with the xe1 and denon 4308 not something ever experienced. wonder whats goign on here. obviosuly not a dodgy disc but wonder down to mastering/recording or a player/avr/pre-pro issue. hope they get to the bottom of it. any other comments you've seen kazz in relation to this disc ?

My understanding from the AVS thread is that Denon AVRs are not affected. Its primiarly a problem with Yamaha and Okyno/Intergra - apparently they source components from a different place than Denon.

DTS are one of the worst for spreading misinformation............they had that on their site before they even finalized their encoding method..................try and find some whitpapers on their site that explain their coding system.

Not to mention all their hot air about Dolby's Dialog normalization....................yet their new codecs now support this feature........slipped that one under the carpet didn't they, thought we wouldn't notice eh :rolleyes:

As mentioned before, also affected:
Pioneer 91txh
Denon 3808

not sure what mis-information from DTS your talking about macca. I have found bitstreaming of DTS/HD/HR/MA faultless in implemetation and believe the info on their website I'm refering too in the means to enjoy the format is still unchanged on the dts website. I have not seen any misinformation in what there is on their website inregards bitstreaming and the various means to enjoy dts-hd ma.

I really have not had one issue with bitstreaming. And have been using players for both formats for bitstreaming as soon as they were avaialble. Been quite a while now and countless discs on either format. Think I would have come across some issue by now.

My understanding from the AVS thread is that Denon AVRs are not affected. Its primiarly a problem with Yamaha and Okyno/Intergra - apparently they source components from a different place than Denon.


could be the case, as mentioned not something found with the denon 4308 which has been faultless. if I hear a pop or anything else you can be sure I'll be the first here screaming about it !

.

In some ways Al ; its good that dts hdma is decoded in the avr [not pcm mixing of course] because of the extra processing power required to decode the more complicated extension packets . One reason between the prices of the 2 denons imo ;) I can see the pana bd50 costing $$$

could be the case, as mentioned not something found with the denon 4308 which has been faultless. if I hear a pop or anything else you can be sure I'll be the first here screaming about it !

Its interesting that onkyo and yamaha use the TI aureous decoder and the denon I believe silicon image ? Dont know about the pio anomaly Macca lists . Ide certainly prefer a cirrus or silicon image solution ; experience counts :)

Ok,

Called Yamaha Technical Support and the guy first said- What is DTS HD MA? Are u sure it is a format? . I said yes so he checked around and when he came back to the phone said I should bring my RX-V1800 to the service centre and quote reference number E1185. I asked if they had the fix and they said yes. :ph34r:

Called support centre and asked if fix available for E1185. The guy on phone went away and checked with technician as he would not let me speak with technician.

On return he said- fix is available on-site. :wub:

CONCERN- Is it really the fix as it was way too easy? Will drop off later this week and try and see the technician to gain confidence; but it could be the technican does what the fix manual states and has no knowledge of the underlying issue. :rolleyes:

The folks that tried reporting problem in the USA yesterday got told it was not a known problem in USA or Japan and for all to register problem. Hmm, something is definitely wrong with this picture!!

Suggest others do same (i.e. call Yamaha music technical support line ) and see if they give the same answer. Post here so we can determine if they understand problem. Don't have the Eagles Disk and have HD-DVD only so someone will need to test. :wub:

That's good work there mate and thanks for passing the info on, fortunately I'm not affected but Yammy owners may need to be looking at this as I played the Eagles track at my place last night with Kazz present and no probs on the 7002 at all and never had it happen on the 2700b either

Kazz could check with XE1 and 3800 as they would have the same fix available and Kamma could do same for RXV-1800 if he has an affected disk.

Then again I believe we live close to each other. I am SE suburbs of Melbourne and could possibly get a disk from one of you and test once my Yamaha is repaired!!

May post this on Reveiver thread also.

Thanks Bryan, I will give them a call later today and see what they say and post back here.

I would definitely like to see a fix for this problem.

Cheers,
