Anyone using a Yamaha
receiver or pre/pro should use extreme caution when bitstreaming DTS MA.
Users are reporting a loud "POP" that is described as a loud firework or gunshot when using one of the above listed receivers AND bitstreaming DTS MA. This can damage your equipment!!!
The theory is certain receivers have a faulty DTS decoder chip and when coupled with certain DTS MA tracks, will cause this issue.
Ronny Katz, the Sr. Manager of Professional Audio at DTS, has already responded to this thread (see post #599) and has stated the issue is not in the DTS track or stream, and to seek assistance from your specific AVR manufacturer. Mr. Katz will not comment any further on the issue.
It is unknown at this time if all or just some models are affected.
Certain members have been in contact with Yamaha and Onkyo, though nothing official yet, it does look promising.
It is unknown at this time if the receivers can be fixed via a firmware or may need a more involved matter like shipping your unit in for a hardware change.
"kinglerxt" has received a reply from Onkyo including a firmware fix for his particular model (see post #1788). Contact your Manufacturer or visit your official owners thread for more details.
In the mean time, I highly recommend anyone using any of these receivers to NOT listen to any bitstreamed DTS MA material.Here's a list of reported titles causing this issue:
**note** There are certainly other titles that have not been discovered yet.-1408
(BD import)-Golden Compass
(review copy)-The Fly
(BD) time-38:52-Fantastic Four
(BD) time-4:22-Hannibal Rising
(HD DVD)-Close Encounters of the Third Kind
(BD)-Eagles Fairwell Concert
(HD DVD) time-23:40-Master and Commander
(BD import) time-17:24-Flight of the Phoenix
Be aware that just because you played any of these titles, does not mean that you don't have a problem as it appears not all titles affect every receiver.
"The Fly" seems to be the definitive test that no one with stated equipment can pass.
**see link below for a video clip of the "POP"**Test at your own risk!!!A big thanks to all forum members that discovered, reported, tested, theorized and most likely solved this issue!!!

Original post left for clarity...
I've run across several posts now saying they have had issues with dts masters when bitstreamed to their receivers. Apparently it causes an extremely loud popping sound that can damage your speakers. (reminds me of when you would send bitstream dts to an incompatible receiver)
-The Golden Compass
It is unknown if this is a disc, player or receiver problem but it only happens when Masters is bitstreamed to your receiver.
Please test at your own risk!!!
Even low volumes can damage your system!!!
If you have watched any of these movies AND are bitstreaming DTS masters to a 1.3 receiver please post your results and what player and receiver you are using.
Also, if you run across any other titles please post.
