I have problem...EVERYTHING works (EPG, nice picture and sound etc.) but one problem is precent:

I have a projector and a receiver and that works very well with sound on every channel. But I also have my HTPC connectet to my 28" CRT for everyday use. For this I have a SVIDEO out.

To the receiver I have an optical SPDIF and to the CRT I have analogue out from my soundcard. I have sound from all channels via the receiver BUT not via the RCA to my CRT. There I am missing the sound on two channels, SVT1 and 2. Theese are sending with Dolby Digital.

So please how can I get sound on theese two channels on my CRT???

This is the only thing not working now. Please help...

You need to downmix the digital 5.1 signal to normal 2.0 analog stereo by setting the parameters on the MPA Decoder config page. Set "Decode to speakers" to Stereo and check the "Downmix to stereo" box. Why not use the receiver also when watching on the CRT?

ok, where can I find the MPA Decoder config page?

On another forum I got the tips to edit the AudioPID. When I press my channel and then press Edit then I see AudioPID and the a value: 4358.

In the right column it sais something Audio1PID and 4358 and further down AC3PID: 4614. If I change the value of AC3PID to 0 the I gets sound on my TV. But if I change channel and then change back to SVT2 the MP has overwritten my value and it sais 4614 again and I have no sound again.

Is it possible to force the value to 0 ??

I have my projector right ahead of my seating and my TV at the right side of my seat.
