The answer is no.

"At this point we should address what can only be characterized as a hoax—the notion that Blu-ray must be technically superior to HD-DVD because the Samsung player outputs 1080p, whereas the Toshiba player is "only 1080i." One high-end home theater retailer told me last weekend that the reason you pay $1000 for the Blu-ray player is for the "higher resolution 1080p output." This is absolute baloney. If you encounter any retail sales rep feeding you this line, keep your wallet in your pocket and leave the store.
The truth is this: The Toshiba HD-DVD player outputs 1080i, and the Samsung Blu-ray player outputs both 1080i and 1080p. What they fail to mention is that it makes absolutely no difference which transmission format you use—feeding 1080i or 1080p into your projector or HDTV will give you the exact same picture. Why? Both disc formats encode film material in progressive scan 1080p at 24 frames per second. It does not matter whether you output this data in 1080i or 1080p since all 1080 lines of information on the disc are fed into your video display either way. The only difference is the order in which they are transmitted. If they are fed in progressive order (1080p), the video display will process them in that order. If they are fed in interlaced format (1080i), the video display simply reassembles them into their original progressive scan order. Either way all 1080 lines per frame that are on the disc make it into the projector or TV. The fact is, if you happen to have the Samsung Blu-ray player and a video display that takes both 1080i and 1080p, you can switch the player back and forth between 1080i and 1080p output and see absolutely no difference in the picture. So this notion that the Blu-ray player is worth more money due to 1080p output is nonsense."
