DTS HD playback glitch.

[Paulo Roberto Elias]

Please read posting #4 for some rectification on the topic!

This is in reference to:

Philips BDP8000/78
Firmware version 1.56
Onkyo SR-605 A/V receiver - HDMI

I am quite sure that there is glitch in the latest 1.56 firmware or in one of its previous releases:

When playing back Blu-Ray discs with DTS HD HR 6.1 the sound playback starts with intermittent dropouts. This issue never happened with my previous BD player (Panasonic BD-30), and therefore it is not the receiver's fault.

Curiously, if I press the audio button on the remote while the disc is playing and change the codec to, say, Dolby Digital 5.1 EX and then change it back to DTS HD HR 6.1 the receiver locks into the latter and plays the soundtrack without interruption.

Interestingly, DTS HD MA 6.1 tracks plays back as 5.1, but I don't know whose fault is it, the receiver's or the player's.

I have read postings over the Internet about this issue, but I could not find any workaround and nobody could really ascertain if the Onkyo/Integra receivers are the culprit or not.

Theoretically, it should not happen when the disc bitstream HDMI is sent to receivers.

DTS HD MA 7.1, on the other hand, plays correctly with all my previous and current playback gear, and it does not seem to produce much problems elsewhere.

F.Y.I.:

1 - Lionsgate releases are the only BD that I own containing DTS HD HR 6.1;
2 - Lord of the Rings is reported by some postings as DTS HD MA 6.1 but neither the disc's menu or the receiver will identify it as such, but as 5.1;
3 - None of the BD with DTS HD MA 6.1 that I own will play as 6.1, but as 5.1.

It seems to me that the DTS HD HR 6.1 glitch can (and it should) be corrected in a future firmware release.

As for the DTS HD MA 6.1 flaw I am not sure if a firmware update can correct it. I had a previous DTS HD MA playback distortion with a couple of Universal Blu-Ray discs that were immediately corrected via firmware in my previous Panasonic BD-30 player.

However, in the not so distant past, the Dolby Digital 5.1 EX flag was incorrectly authored in the fist DVDs that contained that option. Dolby Labs admitted that it was their fault.

Ultimately, there can be glitches at the disc, player and receiver's levels, and the only way to be sure is to try different gears or hope that someone will identify them before you.
