In my crawling around the internet I came across mention of the software powering the Xbox 360’s HD-DVD player on the Xbox team’s blog. It seems that due to lack of dedicated hardware they are doing everything in software which is fine as long as there is enough CPU power to spare. Apparently it pushes the hardware more than any game currently released with it’s 4.7 million lines of code. I couldn’t help noticing this comment though…
“Unlike DVD, where typical players pass the audio data from the disc through to your receiver, HD DVD requires that players mix sounds from menus and such in with the audio being played for the movie. The 360 player software decodes all the above codecs in software, mixes anything that needs to go together, re-encodes it into Dolby Digital and then sends that to your receiver. So, don’t be alarmed when your receiver still says “Dolby Digital” even if you’ve selected DTS in the menus. ”
Now I’m not 100% sure about the minimum level of AC-3 compression that can be used with Dolby Digital but on the surface this would appear to be taking a superior sounding format (DTS) and re-encoding it in a worse one (Dolby Digital) losing detail on the way. Even if the final compression is not very lossy, any compression at all is still subtracting quality beyond the original DTS compression. If they can encode lossless Dolby Digital and stream it to the receiver then to some degree I might be concerned for nothing, but I don’t believe S/PDIF supports that high a bandwidth.
This worries me and really makes me wonder what they’re doing with the video. At the very least, the whole “decode, mix and re-encode” thing seems to be a completely dumb idea for something like HD-DVD which is meant to be a next generation format.

Had a busy few days (I always seem to be saying that lately). My nephew was staying over recently and as usual we talked music and got in some gaming. Multiplayer Civilization IV to be precise. It’s really the first time we’ve given it a proper go multiplayer and it works reasonably well. There’s still a few timing issues fighting wars against human opponents but it’s nowhere near the mess that Civ 3 was. It also settled a question that I’d been pondering for a while related to the in-game “Powergraph” used to compare your military strength vs your opponents. I had suspected for a while that it was more about raw unit numbers than technological superiority and if true, that it really didn’t tell you anything particularly useful regarding whether or not you could beat an opponent in a fight. As it turns out, my thoughts appear to be correct after managing to win a war despite having a much lower power rating purely by being a generation ahead in military tech.
I’ve also finished the “F.E.A.R Extraction Point” expansion pack. It was surprisingly long for an expansion. Overall it was a fun ride although the ending was a little anti-climatic.
My Powermac G5 had been crashing a little lately. It would just freeze within 30 seconds of being started and nothing would fix it short of a reboot. My intuition told me it was RAM (Some of which was cheap “Legend” brand RAM) but considering it’s been running fine for over two years it seemed unlikely. Anyway I pulled the two high spec 1GB Corsair sticks out of my Windows box and swapped them into the Mac removing all the old RAM. Problem gone completely. For now I’ve swapped the other stuff into my Windows box and downclocked it to ensure stability but with only two slots in the PC and a desire for speed/stability, I really need to buy some more RAM. That’s twice now buying poor RAM has caused me problems, this’ll teach me to stick to RAM I know to be bulletproof like Corsar, OCZ, etc.

It’s been a long time since I’ve laughed at a game trailer as much as this one. “Oneechanbara Vortex” which, based on my limited Japanese skills, translates as “Older Sister Sword Battle Vortex”.
Not one for those who have something against lots of blood and/or skimpy bikinis.

P.S. This requires Flash.
P.P.S. It doesn’t seem to matter which option you pick, it still plays the same video.
