there are some cheap ac3 headphones floating around the internet, yes I know, its a stupid idea, probably why they sell for like $15. it wouldnt be hard to take those and make a phono jack output, $15 and a little soldering and you got your hardware demixer.
That would be great, but , where can i buy these headphones ?
Ok, thank's for the replies.
In fact the computer streaming idea is not good for me, cause i want to watch tv on my tv room, and i don't have a computer there.
Buying a dm800 is not worth neither as i don't have HDTV here and don't need the other functions of the dm800, the dm500c is great for me, except for the AC3 bug.
So now i have to look for an AC3 to ANALOG converter board, to put inside the DM500C, that's going to be the best way i can figure in my case.
Do you know about any projects, or anyone that have done one project like that ?
Its just a digital to analogic converter, that goes before the optical system on the dm500c.
And by the way, the AC3 audio is not delivered on the SCART output neither right ? Only on the optical digital connector ?
Thank's
Please provide some information about the hard- and software used.
Box type:DM500C

Please, my provider transmits only AC3 audio on some channels (a lot). But i don't have a digital receiver. Are there anyways i can make the DM500C decode the AC3 audio and output it to the analog RCA jacks ? Or are there any AC3 decoder boards for sale ?
I mean, i can install an AC3 decoder on my pc and watch divx video with ac3 audio, why can't this be done on DM500C ???? Is it possible to implement it on the current images ?
Here's an example of 1 channel that have only AC3 audio

==========================================================It's very strange.
I mean, if i want to watch a divx with ac3 audio on my computer, i just have to install the ac3 decoder.
Why there isn't an ac3 decoder for the DM500c ?
Is that possible ? I don't have a digital receiver, i can only usa RSA output.
I have the same problem on some channels here (DM500C).
No audio, but in my case, my provider broadcast AC3 audio on some channels and MPEG audio on others.
I don't have a sound receiver with a digital spdif input. So i use the RCA output to plug it to my TV.
So the channels that have AC3 sound i get no sound, cause i can't use the digital spdif output.
Are there any ways the DM500C can decode the AC3 sound and OUTPUT it to the RCA ANALOG AUDIO JACKS ?
Here's an example of 1 channel that have only AC3 audio
