Both HD DVD and Blu-ray support the same audio formats: DD+, Dolby TrueHD, DTS-HD (and PCM). So, I think it should be safe to upgrade the AV receiver as soon as all three of these new codecs are supported, regardless on whether the format war is over or not.long_time_DNC said:True, but there's no point in upgrading my A/V preamp (whenever the new formats are supported) until the format war is over...
In the meantime, you can enjoy DD+ (over 5.1 analog or 5.1 LPCM HDMI) with your existing AV receiver, thanks to Toshiba-provided DD+ decoder.
