The BDP-1000 is an ideal choice for those with HDTVs looking to upgrade their DVD player rather than investing in a games console like the PlayStation 3 (which, at time of writing, is slightly more expensive when you factor in the cost of the HDMI cable and Bluray Remote Control).
There are other downsides to the PS3 - namely it's poor connectivity, support for high-end audio and the noise it makes. At the end of the day, there is no point buying both, but if you're serious about home cinema this may be the better choice as it will be easier to connect to your receiver and won't sound like an airplane taking off during the quiet bits of the movie.
However, here's a bit of helpful advice - visit Samsung's UK website and download the latest version of the firmware for the player. You need to burn the image file you download to a CD (using a program like Nero), then put it in the drive and it will update automatically.
If you stick with the firmware provided with the unit, you may have trouble playing some of the new Bluray discs. However, upgrading solves this problem.
People talk about the 'format war' between Bluray and HD-DVD. However, like most recent format wars, the trend is for hardware to support *both* formats after the initial batch of single-format players. Look at DVD-R and DVD+R for example. Most modern DVD players and recorders support both formats.
Samsung have already released plans for a player that supports both HD-DVD and Bluray, but it may be a year or two off (players with this capability are already available in the USA). You can safely invest in Bluray discs knowing you'll be able to play them many years into the future.
In the meantime, all you need to know is that Bluray is the technically superior format, is in hundreds of thousands of households already (in the form of the PS3) and (at time of writing) has a much wider selection of quality movies available in the UK than HD-DVD.
This isn't so much of a war as a border dispute - in the future, I can see both formats co-existing quite happily.
