Who makes blue-ray w/universal player ?

Blu-ray is a higher resolution video format than DVD. If your TV can handle 1080p, 1080i, or 720p, it will be a big step up in video performance from DVD. If your TV is old or small, you might not see a big difference.

The Oppo BDP-83, or BDP-83SE, will play all that you have listed. Go to their web site to read the details.

A DVD player can't be upgraded to match the high resolution Blu-Ray performance. That's sort of like trying to upgrade a VHS player to match DVD. Can't be done.

if this is a long term piece check out RAM of riverside for the upgrade to the oppo deck youll never look back

I should have added that Blu-ray discs also will give you access to hi-rez audio and codecs that typically are not available on regular DVD.

To get a Universal disc player that includes BluRay,SACD,DVD-A,DVD,CD,MP3 the ones that I am aware of are the Oppo, marantz, Denon and soon to be released Mcintosh. I am waiting for the McIntosh before I decide.
I have a 5910ci that will be replaced by the new player.
If anyone knows of a brand I missed I would be interested as well

Soon to be released: Cambridge Audio, Lexicon, Ayre.....
