Changing the environment setting doesn't seem to actually do anything. The environment setting you should be using is "Quiet" because this is when no dynamic range compression is applied.

I wish they made these options straight forward, e.g. Dynamic Range Compression, Off, On, Full rather than a confusing backward system.

Are you sure about that? I thought "Normal" would mean "Range Compression Off".

I agree too about the confusion.

But, at least in PowerDVD and the Azid decoder, "Normal" mean apply the attenuation (DRC) present in the ac3 stream.

"Quiet" or "None" mean don't apply at all DRC, preserving the full dynamic range.

"Half", "Heavy", ... mean apply a part or more than the DRC calculated at encoder time and present in the ac3 stream.

Well these are the options I remember PowerDVD having:

Quiet Environment: Experience the full dynamic range of Dolby Digital sound.
Normal Environment: Experience the compressed dynamic range of Dolby Digital sound.
Noisy Environment: Experience boosted sound. Strongly recommended for notebook users.

Ah, thanks guys. But then Borbus sais: "Changing the environment setting doesn't seem to actually do anything." Hmmmm... Very confusing.

This discussion makes me think that maybe the problems with the 16/24 bit TrueHD output may also have to do with DRC? There's a setting for DRC in ShowTime, but not in the decoder settings dialog.

Thanks for quoting me Borbus. This is something that has been bothering me for some time now. Why can't they just make it user friendly instead of complicating things? As far as I know only DD/AC3 and TrueHD and probably also DD+/EAC3 has metadata used by DRC.

Borbus · 22nd May 2007, 19:51

Am I doing this right? I'm changing the environment setting in the Cineplayer DVD Decoder Options in the Control Panel. It does throw up some weird error when I quite that but the setting seems to apply.

madshi · 22nd May 2007, 21:07

Sounds right to me.

What does this error entail?

"Connecting pins (2) failed."

I have no video track in my evo file, only TrueHD audio.

Do you have the Nero HD-DVD/Blu-Ray registered?

Revgen · 23rd May 2007, 07:59

Is there a way that you could add DTS support too?

For some reason, the libavcodec decoders don't decode the DTS audio from my Basic Instinct HD-DVD very well. There's pops and clicks throughout. The Sonic Decoder plays them fine.

Well, you could try using the same way you need to go for TrueHD, that is: Use EvoDemux to create one EVO file with nothing but one audio track in it. I think this should also work with DTS, although I haven't tested that yet.

Revgen · 23rd May 2007, 09:13

Eh, nevermind. This Basic Instinct track appears to have problems even with Sonics decoder, only in different parts of the file.

Looks like I'll have to use the AC3 track from my DVD version.

Well, going the EVO way I suggested, you'd be using the Nero decoders.

Well, I haven't bought nero yet. It'll take me a month or so before I can afford it. Guess I'll just have to wait.

Does Sonic actually output anything different when you change the settings? I've tried loud, normal and quiet and it always gives me the same output which is dynamically compressed.

I take it I cannot use Nero Directshow filters to playback TrueHD at this point? How is playback of HDDVD and Bluray with Nero Showtime? Thanks

I think you can, but you have to rename the media player to "recode.exe".

Pumpa · 23rd May 2007, 22:22

New Ahead Nero v7.9.6.0, so maybe new filters ???

Strange

I had Clicks ans Pops with Perfume HDDVD DTS (core)Track

First i demuxed it with evodemux and had the cracking in the dts core.
But demuxed with Graphedit and SonicHDDemuxer it plays clean
Maybe you try it

Never had an clicks etc in a HDDVD DTS HD Track with AC3Filter since i demux DTS HD with SonicHDDemuxer
