About Blu-Ray and DVD and Streaming?

[Bruce]

What's the difference in video quality between DVD and Blu-Ray discs? Someone told me that DVDs only play 720p and Blu-Rays play 1080p. I have an LED TV and no surround sound so would I notice a difference? Is it really worth paying an extra $10 for Blu-Ray discs? Also, do applications like Zune on XBOX 360 stream Blu-Ray quality videos since they're 1080p?
Thanks!

DVD's are standard def and this video format was state-of-the-art 70 years ago. A DVD has to be backwards compatible to a 1948 television.

We have learned a LOT about video and monitors in those years, but you dont get any benefit from this with standar def/480 lines of video.

DVD's top out @ 480P. 720P & 1080P are both HiDef. You will notice a difference.
