Not sure what you mean.. Blu-ray discs can hold about just under twice what HD-DVD discs could (HD-DVD is effectively dead as Toshiba no longer supports it). HD-DVD: 15gb single layer, 30gb dual layer; Blu-ray: 25gb single layer, 50gb dual layer. From that standpoint, Blu-ray is superior because high def movies take up quite a bit of space. Esp. when you are shooting for full 1080 size videos. Sometimes people get tripped up over the names of HD-DVD and Blu-ray. The reason those two are tied to the HD format is because these two new disc technologies give you more available storage on one disc, allowing full HD (1080) videos to be stored and played back with ease. "HD" does not mean HD-DVD, it means "high definition".
Whether something burned onto a blank disc on a computer can be played in a particular player depends on the codecs used and supported. Codecs are "compression schemes that store audio and video more efficiently, optimizing for either low space usage or quality per megabyte. There are both lossy and lossless compression techniques." If you use the wrong codec(s), the device you want to play the disc later on will not be able to play the video. It's like asking a person to read aloud something from a French or English textbook when all they can read is German and Italian.
Blu-ray burners are available, though they are kind of pricey and slow at the moment. DVD's work perfectly well for backing up data (I wouldn't want 25gb of data on ONE disc anyway.. talk about all your eggs in one basket), so I will not be abandoning DVD anytime soon. What I look forward to is the roll out of streaming high def sources like Netflix, which currently only offers standard def video. I have an Xbox360 which can act as a media streamer for Netflix videos if you have a Netflix account. No discs to get lost or damaged, just instant video whenever you would like streamed to your Xbox360 hooked up to your high def tv (or any other tv or monitor for that matter).

You're right it is. Keep an eye on what develops with DRM (Digital Rights Management) technologies. Sony has no qualms about using DRM in whatever way it wants and since Blu-ray is THE HD disc format for the forseeable future, it will have great weight to throw around in terms of DRM. Currently, DRM is used to limit what the consumer can and cannot do with the data on the disc he has purchased. Sometimes it is rather loose, other times it is extremely strict (See EA's new game Spore). DRM is used on all types of media, games, videos, music, ebooks, etc. There are sources of DRM free media, but they aren't always the easiest, cheapest, more most legal means of getting it. It is unfortunate that the rise of new technologies like Blu-ray are being used for furthering the industry goals instead of benefiting the consumers, but it's their tech so they can do what they want with it.
