Difference between 24/96 and 24/192

I know that the newer "slim line" DV-440 is rated for 24 / 192 output use with the internal DAC's and is selectable for use with 48 KHz or 96 KHz as a transport through the digital out's. Other than that, i can't remember any specific model numbers or specs. Sugarbrie may know more about these as i know that Stan Warren likes / uses Pioneer DVD's quite a bit. Sean

Just to make sure there's no confusing the issue - even the Pioneer players will only output a 16/44.1 signal thru their digital outputs when playing a standard redbook CD.

Many thanks guys. Sometimes I don't think I could get any thing done without a push in the right direction from the many fine forum members here.

Is there an easy way to determine if a particular DVD player upsamples CD's? I'm looking at the new Yamaha dvd-c920 player and do not see anything in the owners manual concerning cd audio output rates. The only mentions is 96KHz, 24 bit audio DAC for high sound quality. No mention if that is for DVD only.

How do you know the Pioneer models mentioned above output "upconverted" CD audio?

Thanks.
