There has been an upsurge in a lot of HDTV and DVD technology to match it. Because of this HDTV-DVD just got more accessible and easier to find. This means that you will have more choices to choose from as well. But also because HDTV-DVD just got more accessible you may be confused with all the choices. A closer look at the different DVD options and technologies can help you choose from among them. Because HDTV-DVD just got more accessible, knowing what you have to choose from can make the accessibility less confusing.

First of all, originally DVD formats have been around for ten years. The original kind also gave a lot more storage, up to 4.7 GB than most CD's, which are around 700MB. Not too long after this original technology, there came some more technology that made space increase. This was the advent of double-sided DVD's. Some general information regarding some double-layered discs is as follows: single-sided and layered ones with 4.7 GB and 120 minutes of space, single-sided and dual-layered ones with 8.5GB with 4 hours of space, double-sided and single-layered ones with 9.4GB and 4 hours of space and double-sided and dual-layered ones with 17GB and 8 hours of space.

Most DVD's are read-write mediums although there are some that are read-only. There are three different kinds. They are known as DVD-R, DVD-RW and DVD-RAM. All of these can be used to record with. Understanding these basics can give you a lot towards understanding the wide variety of accessibility that is out there in DVD options. Especially when you are trying to understand that HDTV-DVD just got more accessible.

The first option is DVD-RAM and can actually be the most expensive kind. Yet this type can be re-written over and over again. Usually up to 100,000 times over a number of years even. This type is the one that would be more desired for video or film editing. The reason for this is because the disc stores data in no particular order. You must make extra careful however that the type of player you are getting or have will work with this type. This is because not all players are compatible with this type of DVD.

Another kind of DVD is the DVD-R type of disc. This is actually the cheaper option when it comes to recordable DVD's. This type can only be recorded on once though. This is why this type tends to be cheaper however. This type of DVD is also compatible with most DVD players that are available out there on the market.

The main difference between the last type, DVD-RW and DVD-RAM is how many times it can be recorded on. The DVD-RW can be recorded on more than once. But it can only be recorded on about a thousand times. Which is a lot less than the DVD-RAM, but this type is cheaper than the DVD-RAM. This is best for those who want multiple recording capabilities but don't need too much and want to save money.

The reason that HDTV-DVD just got more accessible is because there are two new types that have become available recently. The two new types or formats are HD-DVD and Blu-Ray. Toshiba and the second kind by Sony develop the first one. They are very common but cannot play each other's players. HD-DVD can store 15GB on single-layer and 30GB on dual-layer, while Blu-Ray stores 25GB on single-layer and 50GB on dual-layer. HD-DVD can hold 8 hours of space and Blu-Ray 9 hours.

As you can see with so many options now available you see how HDTV-DVD just got more accessible. Hopefully this information will make it easier to understand, even if HDTV-DVD just got more accessible. With the different types more clearly explained your decision should be easier now.
