in my DVD player? Just wondering why the blu-ray disk didnt work in my dvd player?
 
dude its a high definition format. its meant for a blue laser. hd dvd's can play in a regular dvd player though.
 
You need a DVD player that's Blu-ray compatible.
Blu-ray is a DVD capable of hi-def replay.
 
Blu-ray doesn't work in a regular (old) DVD player because the information on the disk must be read by a new type of laser. I haven't done side-by-side tests, but a DVD is pretty sharp to me and I see no reason to spend hundreds of dollars on a new TV (which you need to see the effect of blu-ray) and a new DVD player. The DVD companies are just trying to sell more stuff; a regular DVD is just fine (and cheaper).
 
Really?

Blu-ray is a completely different technology from DVDs.

Blu-ray takes a completely different laser than dvds.

Now, the Blu-ray laser is Backward compatible, meaning it can read the old DVDs, but the old DVD laser is not advanced enough to read Blu-Rays.

Don't worry about it though.

Blu-rays will not be around for long.
