The amp is connected to the media centre via SPDIF. I am currently using the onboard sound as the soundblaster currently has major driver issues in Windows 7.

DVD's play in Media centre using Dolby decoding on the AMP just fine (Dolby digital shown on AMP). I also get down mixed (From HD soundtracks) DTS from Totalmedia theatre playing blu rays fine too. However I am struggling with Freeview|HD. 1 and 2 sound horrible with the amp set to auto as it defaults to Dolby surround and tries to matrix out the crap that TVNZ is sending out currently. I had a complaint from my wife last night that the news sounded like it was coming from under a pillow. I had to agree that it does sound bad.

TV3 does sound a heap better however when shows that have 5.1 are playing the amp is still saying that the source is Dolby surround not Dolby digital.

Any ideas on how to get the sound, sounding better via media centre? I know a good start would be for TVNZ to get with the game....

I was thinking about this last night. I have a very similar issue. My HTPC is running from the on-board SPDIF to the Amp (Marantz SR5002) and outputs movies correctly based on their encoded audio.

When watching TV however if i set the Amp to 'Virtual' i get TV3's 5.1 broadcast audio fine, but have to change it back to 'Auto' for every other channel and when the 5.1 source isn't being broadcast.

If i choose any of the Dolby options on the Amp i get a slight muffling and/or sync-like issues with the audio. It just doesn't sound right. The Amp does seem to recognise that a 5.1 source is being played though as it shows all 6 speakers as being enabled on the display and then switches back to 2 speakers when adverts come on.

I was thinking it must be an audio pass-through problem/issue but wasn't 100% sure i had a wrong setting on the Amp somewhere.

As with Nety though, if someone has any light they can shed i'd be quite appreciative.
