Should I get an Blu Ray Player or a DVD UpConverter?




Rayford


I have an Xbox 360 running HDMI on a 32" 720p tv. Will a DVD Up-converter do a better job? Or should i just wait to get a Blu Ray Player? Or, on my tv, is it even worth it to get a blu ray payer?


Answer
On a 32" 720p HDTV the improvement of Blu-ray over DVD will be small. And if you are watching DVDs on a Blu-ray player it may or may not be better than a DVD on an upscaling DVD player ... it depends on the quality of the video processor chip. Many upscaling DVD players don't do a great job, but more expensive ones (say > $60) aren't bad. On the other hand cheaper Blu-ray players (say < $150) generally don't do a great job upscaling DVDs either.

So really your choice is a "better" upscaling DVD player or a "better" Blu-ray player. Since you won't get much benefit from Blu-ray disks on your current HDTV unless you plan to upgrade it in the next year or so I'd opt for a "better" upscaling DVD player. The best choice is a used OPPO player. They are now discontinued, but the DV981 (See link) was generally considered one of the best upscaling DVD players ever made, so try to find one of those used.

FYI, I watch DVDs on a Blu-ray player that does better than average DVD upscaling and display via a 1080p projector on a 110" screen. While Blu-ray disks are a bit better, in most cases DVD looks pretty darn good. So, even though I can play Blu-rays I more often than not still buy DVDs because they are usually much cheaper ... and few movies really warrant Blu-ray.

Hope that helps ... Good luck.

can u play blu ray disc on normal dvd players?

or do u have to have a special dvd player


Answer
You need a Blu-Ray player.

The Blu-Ray disc is a new kind of disc. It's certainly the same shape as a DVD, but the pits (the tiny bits that encode the data) are much smaller. A normal DVD player uses a red laser to read the DVD disc (and usually includes an infrared laser as well to read CDs), but the Blu-Ray players incorporate a blue/violet laser. Since this laser has a smaller wavelength, it can read the smaller pits on the Blu-Ray disc. That's how they get 50GB on a Blu-Ray disc, whereas a DVD would normally store about 9GB on the same 2-layer disc.

In additional, all of the software on a Blu-Ray player is different. The menus and all are written in a version the Java programming language. The audio and video formats are higher defintion, and can include not only MPEG-2 video, but VC-1 (formerly known as Windows Media 9) or AVC (Advanced Video Coding, part of the MPEG-4 specification).
So even if you made a Blu-Ray disc using the plain old DVD media, DVD players wouldn't understand it.

However, Blu-Ray players do play DVDs.
