50GB is 25GB times 2 so twice as much memory

since it has more space, they don't have to compress as much and they can use a higher quality audio.

While a movie on a BD-25 can still have really good PQ and AQ, like the other people said, it's all about the memory.

Would you rather have $25 or $50? You can buy more with $50, just as you can fit more data on a BD50. Instead of using 2 discs for a short TV season, they could probably just fit it all on 1 BD50.

So that Sin City release in Canada on BD25 without extras, do people believe the transfer will improve when it comes out in the States? I mean, since the movie has no extras, I'm assuming it occupied the maximum capacity of the disc. On BD50's, does the movie occupy greater than 25gb?

If the movie fits with maxed out bitrates for video/audio, it really doesn't matter if it's on a BD-25. Only if it exceeds or needs more than 25 gigs, will I really care if they use a BD-50.

Shorter films with limited extras can do just fine on a BD-25, even with high bitrates. I've seen BD-50s with over 25 gigs of unused space - so what's the point in those situations? Just to appease people who would have complained if it was a BD-25?

Technical Police here..

BR / DVD / CD / Hard Drives do not use "MEMORY" to store data..

Sorry I just hate it when people say they are running out of memory or saying memory when they really mean hard drive / storage space.

BD25s are single-layer discs, BD50s are dual-layer. You can usually tell if a disc is single or dual layer by looking at the inner ring on the data side of the disc: if there are two sets of codes imprinted (one usually looking just a tad 'deeper' than the other), it's a BD50.

If the transfer doesn't require more than 25g of space, then I see no problem using a 25g disc.

When the encode is optimized for a BD50 disk the picture looks almost 3 dimensional. The quality of the picture can look amazing and it really pops off the screen. Typical BD25 encodes look flat by comparison. Just compare the best Disney BD's with any WB movie and you can see a big difference in terms of PQ. I realize that there are other factors to consider too (film condition/encode processing, etc...stuff I know little about).

I am not sure if this matters but I notice that the bitrate meter never exceeds 20 MBps with BD25 media and often times exceeds over 30 MBps with BD 50 media. In this case the higher bitrate equates to a better overall picture.

The quality of a BD50 optimized encode helped win the format war. This was something that HD DVD could never accomplish.

In summary, all features should be optimized for BD50.

That's almost laughable. No it didn't, it had no effect on the format war whatsoever. The war was one of politics between studios and manufacturers - consumer preferences and disc quality had NOTHING to do with the outcome.

If you believe otherwise, you are incredibly naive.

50GB is still better because you have the opportunity to hold more space than on the 25GB disc. Sure, if you only need a BD25, save the money and put it on there. But if a title can have extra features that can fill up a BD50, why not?
