Can you only play Blu-ray movies on a ps3?

You can play Blu-Ray Movies only on a Blue Ray Player and the PS3 is also a Blue-ray player along with a game console. All Blue-ray Players will also play DVDs and CDs and many like the PS3 will upscale them to near 1080P quality if set up to play Blue ray discs in 1080P. My PS3 plays DVDs so much better that I have not used my DVD player since I saw the first DVD play on the PS3.
