    The article is a total crock of @#$#. Just looking at the charts shows you that the audio "difference" is so incredibly tiny that the actual players probably have far more to do with it than the format.

    I didn't read the article, but I knew it was a crock by the audio "difference" thing.

    AFAIK, the audio on both formats is the exact same (and the same as standard DVD as well). DTS (the best) and DD. Now some content is encoded better into DD or DTS at the studio, but the delivery of the digital information is for all sake of argument the same 1s and 0s that were put on the disk at the studio.

    Actually, I have heard that since the data capacity of the newer disks is so great that many of the soundtracks are uncompressed (raw PCM data), but still AfAIK there is no difference between the formats in the audio realm.

A standard two hour movie will fit on a DVD5 at 720p with 6 channel AC3 audio and a bitrate of 4.5-6 mbit/sec. While this wouldn't look great using xvid, H.264/AVC High profile can create great quality. x264 using Sharktooth's HQ-Slowest profile is very impressive. A 2 hour movie can fit on a DVD9 at 1080p at 7-8 mbit/sec, again with very good quality.

    Hell, I've seen some 2 CD sized x264 rips from 1080p sources that blow DVD out of the water. Forget about the MPEG-4 ASP codecs like Xvid and Divx. Now that we have H.264/AVC, we can achieve excellent results at 720p and 1080p down to DVD5/9 sizes.

    I disagree with the analogy here between HDDVD to Blu Ray :: DVD-A and SACD.

    DVD-A and SACD had/have their issues due to a number of reasons. SACD is Sony, and that is enough of a reason for failure (even with a Sony receiver and a Sony SACD player it takes separate wires to play a SACD than a CD or DVD, dumbasses*).

    Also HD CD formats are not backwards compatable (mostly) with existing technologies like MP3, regular stereos and car stereos.

    Now, HD video is going to take off in some way. Why? DVDs and SD content don't look very good on your brand new HDTV. 1080[ip] and beyond content will blow you away compared to SD stuff. Even non-technical people can tell the difference between HD and SD, but most people are not that tuned towards audio. I guess it has to do with 1/2 of the human brain going towards vision or something like that.

    Why do servers have AC to DC power supplies at all? I don't know about you, but I have my servers on UPSes. So the whole thing goes AC from wall to DC in the UPS to the batteries then from DC to AC to the computer where it converts it back to DC.

    I'm not an EE, but why cant AC come from the wall into the UPS and then the UPS spits out DC to the computer?

    Granted the UPS power supply needs to be redundant because they are the 2nd most likely thing to fail in servers after disks, but what am I missing here? I know there are telco grade computers that take DC, but these are not available in many options and are typically lower end boxes. But to me, none of these additional conversions to AC and DC an back again with the added likelihood of a failure anywhere in the chain seems a bit non-optimal.
