DVD Players are still a great way to watch movies, whether it's for the kids or as a spare unit. The resolution may not be FHD however laser DVD players can upscale to 1080i with great results.
If you need a player wiith superior features, native 1080i resolution and with all the high-quality home theatre style features such as digital audio 5.1, 7.1 and premium Dolby surround sound, then a Blu-ray player is for you.
Some other key differences between the 2 types of players are that Blu-ray discs can only be played in Blu-ray players. Whereas, DVD's can be played in either player. Blu-ray disc capacity is also up to 10 x higher than a DVD, which means video play back will be of much higher quality. This includes gaming and other content.
