Quote: "I obviously prefer Blu-Ray format to DVD now that I have a drive. But from what I understand, HD-DVD and Blu-Ray offer the same kinds of benefits. Both output up to 1080p, with top of the line sound capabilities. Isn't this kind of like comparing two different brands of umbrellas? They both help keep out the rain and do virtually the same thing, but they're made by two different companies."
1) Last time I checked BD had twice the reading speed then HD-DVD. This is possible because the data on a BD is stored much closer to the laser while HD-DVD stores the data in the middle of the disc (like DVD). This is also the reason for the higher cost of BD as a protective layer has to be applied to protect the data because it's so close to the surface. HD-DVD is not fast enough to stream 1080p, only 720p and 1080i. This is why BD is considered (or just marketed as) full or true HD. If there's any new info on this I'll gladly take a look.
2) A standard BD disc can hold 50 GB while a standard HD-DVD can hold 30 GB, these are dual layer configurations and both can be made with more layers (I think BD was made up to 200 GB) but regular players can't read them.
3) BD is so much easier to type then HD-DVD
I should point out that HD-DVD upscaled to 1080p so far looks very much the same as BD (from what I've heard). I don't know what the difference is with high quality media and a large high quality TV though. BD have suffered much initially from bad quality media, thus people have stated that BD looks worse then HD-DVD but it's not the disc at fault since it contains digital data.
