HD DVD vs Blu-Ray Disc

Whats the difference. There are many difference in HD and Blu. Blu ray, on average, holds about 60% more data then HD. The bit rates are faster on Blu, in every catagory, that I have seen. It is, in most cases, more advanced then HD. A downside to Blu discs is the way they are made. When recording them, the tilt the laser on a different angle (which is why you cant play blu ray in hd players and vice versa) which allows them to store data closer to the surface, for more room. The problem with this, is scratches are potentially more harmful to the disc. To fix that problem, Sony coats the disc with a specially designed coating. This is supposed to be extremely strong. But it costs more. Also the technology is a little more advanced, so the players cost a bit more.

Now for a while Blu ray players have been selling more software, and more hardware then HD. But HD is claiming to be catchy up, and actually passing Blu-Ray. But a recent discovery in the numbers show that HD is not counting PS3 as a Blu-ray Disc player.

Should Ps3 be counted in? Is Sony just pulling out another beta? Who do you prefer, and why?

    You missed the point that many of the Blu-ray discs are encoded in Mpeg2, while most of the HD-DVD are in VC1 – a compression more like Mpeg4/DivX. So while they might have greater capacities for the most part it’s Blu-ray’s advantage is thrown away through using less efficient encoding technology. Blu-ray can use better technology, but few of the early discs have chosen to use it.
    Neither format is winning anything currently, they’re both failing.

    Hmm, pretty damn interesting, I didn’t know BluRay used mpeg2, that seems kind of retarded since that technology came out years ago…

    to respond to the first comment, blu rays are not just encoded in mpeg 2. they first came out as that but they started to offer playback for the 3 main types, which are mpeg4 mpeg2 and vc1. vc1 and mpeg4 are sort of competitng types. the mpeg2 was initially because it was needed for playback of regular dvds. vc1 mpeg2-4 are all used in blu rays at this point. depending on what the publishers want. it was also easier to integrate the protection data to the mpeg2 but it is just as easily set into all formats.

    and by failing, im not sure exactly what you mean, because both are actually pretty successful.

    Is HD-DVD counting the sale of Xbox 360 HD-DVD players as units sold?

    If so, then PS3s should definitely be counted. If not, then no.

    If ‘success’ it judged in terms of the percentage of machines and discs sold compared with DVD, the dominant format, then they’re not. How are you judging their ‘success’?

    chicagojosh, both sides are counting all players of whatever type, including PC drives. They’re also counting all the freebie King Kong and Casino Royale discs and vouchers for free movies included with many players as ‘sales’. Which demonstrates how desperate they both are to make it look like they’re getting somewhere.
    European sales are especially poor, where HD-DVD possibly leads. But probably only because the PS3 has effectively bombed here, due to it costing 70% more than the US price.
    One HD system will ultimately rule, but I’m unconvinced it’s either HS-DVD or Blu-ray, it might be an online format.
