Will an upconverting DVD player be much better than the XBox 360 stock DVD player?

Question

I just bought an XBOx 360 and a Plasma Television.

I am using the HD outputs from the XBox to connect it to my TV.

The XBox built in player is progressive scan (but not HD or upconverting).

If I purchase an upconverting DVD player will I notice a real difference in the image quality?

Answer 1

Upconverting DVD players are not considered HD either.  They upscale to 720p or 1080i, but it is considered near-HD.  The quality will be the same as your Xbox360.

If you want higher quality, then purchase the HD-DVD drive for the Xbox360.  HD-DVD are recorded in 1080p rather than 480p.
