Blu-Ray players are compatible with DVDs
Bluray players are backwards compatible so they will play standard DVDs as well as Bluray discs. Note that although the DVD is being played by a Bluray player, it does not make it HD quality. Some bluray players will up-convert the standard definition image from 480 or 576 lines up to 1080 lines but although the format is HD, the image quality still remains standard definition.
HD DVD and Bluray were competing high definition disc formats. In 2009 HD DVD was withdrawn from sale as it became apparent that Bluray had won the HD disc battle. The two formats are not compatible so HD DVDs can only be played on an HD DVD player.
people who have bluray players
First, Blu-Rays are not DVDs. People should not get the two mixed up. Blu-Ray discs will only play on Blu-Ray players and those will only work on HDTVs. Blu-Ray players can play DVDs, but DVD players are not compatible with Blu-Ray
Yes they are. Bluray players have an HDMI output for their high definition signal output as well as analog connections for compatibility with displays that are not HDMI compatible.
Most Bluray players can play either DVDs or Bluray discs using a standard definition television. Almost all Bluray players have an analog composite, S-video or component output that can be used. Before purchasing, check that the player has an output that the television can accept. Note that the quality of the image will be standard definition and not HD. All Bluray players today limit their analog outputs to SD so even with an HD television, analog inputs will not deliver HD images.
No. DVD quality will be displayed whether the player is a DVD player or a Bluray player. DVDs won't be the same quality as a Bluray disc of course.
