Lossy blu ray's with less than 1.5mbps bitrate

[theprestige85]

Ok, I don't have one of those high end receivers that decode Dolby True HD or DTS Master or whatever, but I am able to get the 'core tracks' of the blu rays.

I was under the impression that all blu ray's that supported DTS automatically bitrates at 1.5mbps to compensate for the compression. However, i've been testing quite a few blu rays these days, and some of them are still DVD birate.

All Artificial Eye blu's that I own have been displaying 740mbps on my PS3, including the Three Colours Trilogy and Double Life Of Veronique . Now, they still sound decent, but it's frustrating that it would have such a lower bitrate than they should.

I was very surprised to find that Drive had a similar bitrate too, maybe 760 or something, and while that too sounds alright, it didn't sound nowhere near as amazing as it did in the cinema.

I know, I know, cinemas use far superior sound systems, however, for a lossy amp, my system is pretty decent, I feel. I've got a Pure Platinum Digitheatre 5.1 system, and while it may be about a decade old and not lossy, it's still high quality sound with good frequences and a clean yet deep subwoofer.



Anyways, anybody else with lossy tech find some of their blu's have low bitrates??

Drive, really ?! My blu looks and sounds top notch!

740 MBPS! And i'am not getting you , you mean to say Drive's Blu-Ray's DTS HD-MA track has bitrates averaging 760 kbps? (which is just not possible) , even the core track is DTS 1536 Kbps (1.5 MBPS) , and the same goes for each and every movie whose Audio is encoded with DTS HD-MA. (I mean they all have DTS 1.5 Mbps core in them + additional data which makes them lossless) ,so their Bit Rates under no circumstances can be lower than that. Lossy Tracks however are a different story and they can be anything AC3 448 Kbps , 640 Kbps , DTS 768 Kbps etc , but the disk will still include a lossless track.

Any Blu Ray that contains a DTS-HD MA soundtrack should provide you with a 48KHz 1.5Mbps core audio track. Whereas 768kbps is standard DTS.
Have you checked the settings on the PS3? There are a lot of audio frequencies which are automatically unchecked by default.
Also, you are actually selecting the HD track on the disc yes?
Not being funny but just want to eliminate the easy things first!

Have you achieved any 1.5Mbps playback? This would at least confirm your settings are correct

The core audio track is not always 48kHz/1.5Mbps. It can be 48kHz/768kbps.

Sorry, about 768kbps to be more precise. I am actually referring to the LOSSY tracks and not the lossless ones since I don't have HD sound capabilities.

I'm telling you, i've double checked and everything, and my settings are on point. Optical sound and i've chosen Bitstream Direct, which shows me the exact bitrates for the film I am watching. You are right in that most of the DTS Master films are 1.5mbps, and most display that when I do watch a film. However, my Artificial Eyes and Drive blu's only have it at 768.

Definitely already eliminated the easy stuff, mate. I make sure i always select the HD track just in case too.

All the frequencies that my 5.1 sound system can handle are ticked and everything. It does display the 1.5mbps on most blu ray's I watch, just not the ones I have listed. I've come to the conclusion it's because those particular discs have added a 2.0 lossless stereo option, so maybe it's a space issue for the distributor?

It's a bit annoying because I know a film like Drive can sound a LOT fuller than it sounds, even if it were just to be a high birate lossy track.

Yep, if your getting 1.5Mbps from some discs you must be set up correctly so I guess it's just those particular discs that happen to have 768kbps core.
