The short answer is, YES! Blu-ray is the king of the hill in consumer video products and offers a performance superior to anything that has ever been available before.

Blu-ray's larger storage size means that it can hold true high-definition video and uncompressed audio signals, far surpassing anything that DVD is capable of. Also, video is stored on Blu-ray discs in a format called 1080p/24, which means that many modern TVs can play the image back at the same 24 frames-per-second that was captured on film, reducing a motion artifact called "judder." 

Because a Blu-ray is connected directly to your TV, it isn't competing with other channels for bandwidth, so it can deliver a superior high-defintion experience compared to that of HD cable or satellite.
