Be Aware of Both Formats
Blu-ray and HD-DVD both utilize new Blue Laser and video compression technology to achieve high definition video playback on the same size disc as a standard DVD.
Even though the underlying concept of Blu-ray and HD-DVD are the same, the way they are implemented is slightly different, resulting in two incompatible formats (remember VHS vs BETA).
Know What is Available to Play on a Blu-ray Disc Player or HD-DVD Player
With HD-DVD now officially discontinued all of the major studios are now releasing their high definition content on Blu-ray Disc. There are now very few releases coming out on HD-DVD. However, there are some great HD-DVD disc bargains on secondary market sources, such as eBAY.
Your Current DVDs are not Obsolete If You Switch to Blu-ray or HD-DVD
Also, when playing a standard DVD in a Blu-ray Disc or HD-DVD player, you can view it at standard resolution or have the player upscale the DVD playback signal to match 720p/1080i, or in some cases, 1080p mode, which will be a better match on compatible HDTVs.
Most Blu-ray Disc and HD-DVD Players Also Play CDs
Know the Types of Connections Blu-ray Disc Players and HD-DVD Players Have
Two additional outputs:
1. HDMI, which can transfer high definition video and digital audio to a TV or AV receiver that is equipped with an HDMI or DVI-HDCP input via an adapter.
2. 5.1 channel analog outputs that transfer a decoded surround sound signal to AV receivers that have 5.1 analog inputs.
You Need an HDTV to get the Benefits of Blu-ray and HD-DVD
NOTE: Although high definition resolution can be accessed using Component Video connections of a Blu-ray or HD-DVD player, this is at the movie studios' discretion. In the future, discs may be encoded to limit access to high definition resolution only by the HDMI connection.
Know How Much Getting Into Blu-ray or HD-DVD Will Cost You
When you by a player in either format, take into consideration the cost of connection cables, as well as the $5 to $10 dollars more for each new Blu-ray. Also, keep in mind that no more HD-DVD movies are being released.

Is Blu-ray and HD-DVD Really Worth It For You?
Also, instead of waiting, you can enjoy true hi-definition Disc right how with a Blu-ray or HD-DVD player, especially if you have a large screen HDTV or HD-video projector.
However, if you are on a budget or don't wish to risk it now, for less than $150, there are DVD players with 720p/1080i/1080p upscaling capability that narrow the gap between standard DVD and Blu-ray or HD-DVD.
