"It is my pleasure to let you all know that the HD DVD udpate for Xbox 360 is slated for release on 5/15 (i.e. tomorrow!). So when you wake up in the morning, you should be able to upgrade your software. And me free from telling you when are going to get it . Hope you all download it and provide feedback on what you think!
And sorry I did not give more of a notice. I was out on the cruise and only now got around to getting the specific time/date for it."
Highlight as per my recollection:
Fix various disc playback compatibility issue
Take DD out of "night" mode for much better sound quality
Add DTS @ 1.5mpbs
can't remember the rest! I'll update this thread with user feedback on how much/if any the audio is improved.
