I have a PCI dvb card in my desktop PC for now till I get the bits together for a proper HTPC.

Anyway, using dvbviewer I have tried both the monogram aac codec, and another one that was put there by something else.

Both sound useless. The status bar of dvbviewer is reporting 24kHz, there is no treble at all - its making the FTA juice in auckland sound hi-fi when compared with the C4 off dtv (I cant watch the HD channels without it just being a slideshow at the moment)

Maori and the tvnz ones seem to be similar, but there is a lot of sibalance there. I cant really tell if I am not getting the SBR part of the signal or if it is just useless audio to start with, but either way its not acceptable. How are others finding it?

Found my DVB-T to be pretty poor on audio too, I don't remember it being bad on DVB-S.
Haven't had too much of a chance to fiddle with it yet, but tried using several different audio codecs and they all sound the same - a bit tinny.
I'm also using DVBviewer, with a HVR3000

Same here, only having audio issues with channels one and two though, the other are acceptable but could be higher bitrate, dvb-s is double or quadrouple the audio quality

Actually its all tvnz channels, have updated all drivers and software, just wondering if aerial is maybe not good enough.

Its definatly not something inherent in he-aac because I can playback 64kbit webstreams on the same PC in foobar2000 that sound a hell of a lot better. If its not going to sound better then a skype call then theres not a hell of a lot of point having a music channel on it.

At a *guess*, I would say its because TVNZ are still in the testing phase for their DVB-T, whereas Media Works (TV3 and C4) have already gone live with the service as of the 1st of April (Not a funny prank, but still cool none-the-less!)
