Hello

I want to playback my recordings from TV One / TV 2 with the Windows 7 Ultimate Media Center.

Media Center and Media Player do play the video, BUT do not play the audio :(

I've googled for quite some time and found this link:

http://msdn.microsoft.com/en-us/library/dd742784%28VS.85%29.aspx?ppud=4

It says:

The AAC decoder does not support any of the following:

Main profile, Sample-Rate Scalable (SRS) profile, or Long Term Prediction (LTP) profile.

Audio data interchange format (ADIF).

LATM/LAOS transport streams.

Coupling channel elements (CCEs). The decoder will skip audio frames with CCEs.

AAC-LC with a 960-sample frame size. Only 1024-sample frames are supported.

I think this is the problem. NZ FreeView uses LATM encoded AAC as far as I know.

Does anybody know how to playback recordings from TV One / TV 2 with sound in Windows 7 Media Center WITHOUT re-encoding the files ?

Thanks for your help

Bernd

Might need to install monogram audio codec. But I undertood with Windows 7 Media center you didn't need to do this.

So anyway here it is if you want to install it.

Nope no need to install anything. Most likely it is how windows is setup to handle audio. Go into the playback devices and check what your settings are. Are you outputting via SPDIF or HDMI? and what are you outputting too?

I've found that Media Player won't play back audio with .TS recordings from GB-PVR either after ZollyMonsta mentioned this a few days ago. I've been meaning to look and try and establish why this doesn't work.

Yes... Trying out streaming between Win 7 and Mediaplayer.. No audio on Media Player on Win 7... however same recordings play fine in GBPVR... Gotta be a Windows or Media Player issue I reckon.

Hello Nety,
I can't see anything wrong in my playback devices settings.

There is only my on board "Speakers (High Definition Audio Device)" activated and it is the default device.

I have a Dell Studio XPS with on board audio and I use the analog stereo output.

I can play and hear songs, but no audio when playing back my TV One recordings.

I've installed Windows 7 Ultimate x86 and the windows updates, nothing else.

Any ideas?

Cheers

Bernd

Hi Psycik,
I've registered Monogram filter successfully now (had to run regsvr32 from cmd as administrator).

But still, no sound.

More ideas?

Cheers,

Bernd

Hello, here is some more info:

I've tested and change the PreferredMPEG2AudioDecoderCLSID of the MediaCenter in the registry to the Monogram CLSID.

But with this changed setting, both Media Center and Media Player cannot open the files anymore!

So I've changed that back to the original value. Now as before, video ok but no sound :(

Playback of the recorded .ts files with DVBViewer works perfect, video and sound ok. But I will use the Media Center in the future.

Please help.

Cheers

Bernd

@Nety -> Your inital comment must be wrong. I've tested this now 4 times with fresh Windows 7 Ultimate installs.
There is no way that Windows 7 Media Center or Media Player can playback the audio which is in the .ts file recordings from TV One or TV 2.
As the msdn site explains, the Windows 7 default decoders to not support this LATM AAC used by FreeView NZ.

How does it work for you? Do you have aditional software installed?

I really want to make my Windows Media Center playback the recordings from NZ FreeView.

Any hint might help,

Cheers

As you have found out Media Center wont play the audio from a .ts stream recorded from DVBViewer or (Insert whatever package you use here).

Why would it???

Why don't you just use Media Center to do the recording in the first place? As Nety mentioned is does support the native decoding of Freeview audio streams, but only when its doing the tuning/recording in the first place. Thats what most people who use Media Center do... :)

If you don't want to do that, and you don't want to recode the files (DVMRSToolbox will probably put them into a .WTV container without re-encoding) then your sh1* out of luck...

Ah sorry old mistake of not reading carefully enough. I thought you were talking about MC recordings rather then DVBViewer recordings.

I have not heard of anyone getting playback of ts files via MC. There was a thread some time ago here where some people were trying to get it to work but it did not seem to be a happening thing.

Yes, I guess the hint I missed was Bernd trying to play .ts files, when windows 7 media centre uses .wtv format.

I have Windows 7 MC working perfectly too with no additional codecs - even streams to my popcorn hour with sound on every channel! WAF through the roof, as long as she doesn't ask to watch live TV off the popcorn - only DVB viewer allowed that lol...but we were restricted to AC3 from TV3

I had a similar audio problem with my XPS m1530 high def audio. MPEG files with AC3 5.1 audio would not play audio when played throuh media player if I double clicked them frome explorer. They did however if I played them from the media player library or played them in mediacentre. I realise this is a different type of audio but I wonder if there is some sort of issue with the Dell drivers or setup? I did manage to "solve" it by installing the Shark007 codec pack. I didn't really want to do this and it has "damaged" some things (eg no Dolby logo during playback anymore) but it seems okay and for laptop audio I can live with it for now...

Hello @all,

I apologize for the confusion I've caused.

Thanks for making the situation with the .ts files clear.

I will take my DVB-T Stick tonight and check if recordings done with the Media Center work for me. The reason why I was using DVBViewer is that I like its EPG ;)

To finish this threat, does anybody know an easy solution how to convert my .ts files without "too much" re-encoding? I've got so many recordings and want to watch them with the Media Center.

Again thanks to all of you. Always good to find forums where people do answer questions and know what they talking about ( this is not everywhere the case ;)

Cheers

Bernd
