Standard DVD format on Blu-ray?

If the Blu-ray/DVD combo ever happened, say goodbye to the perks of the high quality transfers. Essentially what would happen to the disk is that they would have to sacrifice half of the storage space on the disc to the DVD format. Thus, they would have to use more compressed audio and video files in order to get the Blu-ray version onto the other half.

There's no loss of quality. DVD & HD-DVD didn't exist on the same surface. One was on the front and the other was on the back. No loss of capacity.

The Twin format of HD DVD actually had them on the same side. Bandai's Freedom is the only disc I can think of that did this. The top layer is DVD while a single HD DVD layer is underneath (appropriate for the sub 1 hour per disc for Freedom)

Experiments have been done for Blu-ray, and of course there was Warner's never-produced flipper format with both HD formats, probably for the same reason why you've never seen the twin format Blu-rays. While they succeeded in making them in the lab, mass production has proven impractical

Disney will be shipping DVDs with their Blu-ray Platinum editions for the forseeable future. My suggestion to you is that if you have an iPod or other PMP, use the digital copies that are going to become very common in the next year or so, and invest in the cradles that let you hook it up to a TV. It's not perfect, but it'll tide you over until Blu-ray players get down to the point where you can buy bedroom/living room units

I wouldn't mind dual formats. I love blu and wouldn't watch the SD version but if I have a new release and I go over to a fellow friends house that doesn't have a blu-ray player or the new movie it would def. come in handy.

So theoretically, a combo BD+DVD disc can be made with no problem. It can even be a BD50+DVD9 disc all on a single SIDE, which means labels can be printed. It was demoed sometime in 2006 by JVC to smack back the DVD Forum but it never went into actual production

yes, but the issue is that the red (or infrared for CD) laser needs to go through the BD layer and hit the DVD (or CD) layer and then back through the BD layer and to the OPU to read the data. DVD players and CD players where not built for that. The issue JVC had in 2005 was that many DVD players (if I remeber correctly near 50%) could not read the DVD level well enough (i.e. play the content like it should).

So it is no where as simple as (like you stated) BD is around .1mm, DVD is around .6mm and CD around 1.2mm

now with .6 and .1 you can make a flipper (BD one side and DVD on the other) as looked at by WB so that you don't need to fgo through the BD layer to read the DVD. But
1) it costs a lot more then a BD and DVD seperate (i.e. yields, cycles and stuff)
2) no one likes flippers
3) people are not interested in paying more for something they don't need or care for, fpor every Darktrader there are 100 Anthony that say "why would I want to watch SD when I can watch HD?"

the first combos where 15/5 (one layer of HD DVD and DVD), so there was loss because there was no way of making a HD DVD-30 but later they got the procedure good enough that they could (with subsidization) have 30/9 disks.

I don't think anyone minds it, the issue is, would you be willing to pay for it and would you care enough when buying (i.e. would it stop you from buying a title if it did not have or convince you to buy it because it has it)?

if your answer is not yes for all of them (and for most people it is not) then it is not interesting for a studio


-------
There was this show here where there where these rich people (investors) that would give money to “inventors” and start-ups they thought worthy(i.e. guy makes spiel to the group why his company/product was worth it and then each of these people would decide if they would invest in the company and how much) In one episode one of those rich guys was an owner of a large pizza chain (it was more or less the same people each show), and the person presenting created a pizza box that is folded and torn into triangular plates for the slices. Even though the guy thought it interesting and looked like he liked the product, in the end he decided not to invest because the pizza stores would not care to raise their cost for tear away pizza boxes, it won’t help sell pizzas (and then seeing that the pizza guy was not interested none of the others went for it either)

The same here, just because it sounds cool, does not mean it makes sense

I dont see dual layer Blu/DVD being something the studios would really want to push anyway, now that Blu has won, they will want to really push blu's! Besides, one thing that always bothered me was HD-DVD always said they had these great sales numbers with titles that were combo discs. Well how in the heck do they know if it was purchased for a DVD person or an HD-DVD person. I just thought it was a shady way of counting higher numbers for the HD-DVD side, knowing probably 75% of those numbers were on DVD side purchasers that didn't even own a HD-DVD player. I say keep em seperate! Soon Blu-ray players will be everywhere and people can play both formats (you know for those rare DVD only titles )! I remember looking back as DVD came out, I was hardly worried about going to a friends house and making sure I had a VHS copy to take along, if they didn't have DVD, the party was at my house!! Trust me to the OP, you'll be re-buying Sex and the City (or what ever title you get for her on DVD) down the road on Blu anyway.
