This is for anyone who has used both and do you think there is much difference in picture on the screen and all of this? Anyone able to tell me more about your experiences with this then?
Blu-Ray by a mile. It’s easy to see the difference on a modern HD set.
It’s enough of a difference that I, tighter than two coats of Kem-Tone, have purchased the Blu-Ray of movies that I already owned in a DVD format.
I don’t care. Sure, Blu ray does look better, but not better enough to justify replacing my entire DVD collection.
I feel like BluRay is kind of like CDs. I missed the entire CD revolution and went from cassette tapes to mp3s. I expect I will do the same - skip from DVDs to streaming all the time.
VHS to DVD was a big jump in features. Bluray just isn’t worth it to me.
DVD
I still have no idea what the big deal is about super HGTV and 4K and what-not. I don’t watch TV to count nose hairs. I watch to see a story or a sporting event, etc. I can make out sufficient detail to enjoy any of that at any current resolution, even 480 or lower.
And I already have a DVD player. I’m not replacing hardware for what I see as no benefit.
Blu-ray all day. To me, the difference between DVD and Blu-ray is significant. I’m not exactly a huge collector of movies though. I think we may have a few dozen Blu-ray at home.
This. It’s annoying to me to have to go back to SD, so I don’t like DVDs.
Blu-Ray also tends to have more/better extra features that DVD versions.
I don’t think I’ve ever watched a Blu Ray in my entire life. With streaming, it’s pretty much dead, and I also am not going to replace DVDs. My player upconverts the image to HD.
I watched a DVD the other day and was frustrated by the fact that the faces of people not right up in the camera lens were blurry/muddy. I wanted to see their expressions, darn it! Blu-ray all the way. I wasn’t initially convinced when it first came out but I definitely am now.
Absolutely true. I care about the story and SD resolution is fine. I’ve watched TV and movies in SD my entire life. I’ve seen HD at store demos and friend’s houses. It’s a pretty picture. But nothing I particularly want or will spend money on
Blu rays copy protection is another turn off. HDMI is nasty. Give me RCA connectors please.
I enjoy Blu-ray for movies like the Lord of the Rings series. Otherwise, I don’t care. Mostly I stream movies, and I watch them on a smaller 27" screen.
I can’t tell the difference, so I always rent plain DVDs versus Blu-Rays at Redbox because they’re cheaper.
DVD (or any standard 720x480 content) looks terrible; especially on large screens.
There is a massive difference.

I agree size matters. 
A giant screen TV pretty much requires HD.
That’s why my TV is a 20 inch model. SD looks fine on it.
I prefer my 2006 TV set with a DVD player. I bought it for $50 since at that time last tube TVs had to be sold.
To those who can’t see a difference, get your eyes checked, or get a better screen. Blu-Ray blows DVD away. If you already have an HD capable screen, you are wasting its abilities with DVD.
To those who say “I watch movies for the story”, I will concede that not all movies need to have blu-ray resolution. However, having that resolution is an extra bonus. An extra bonus that might reveal more about an old favotrite you never knew existed before. But there are some movies that are utterly brilliant in HD that are pointless in SD. So really, it all depends on what you are into, and how much $ you want to invest for the blu-ray experience.
Ditto. Blu-Ray is clearly capable of superior picture and sound than DVD.
Not that it always is, though.
DVDs. I don’t see much improvement in blu rays over an upscaled DVD on HDMI cable.
There is an obvious difference between 480p DVD and 1080p blu ray in the first half of that video. But the second half, where they compare a 1080p blu ray vs a DVD upscaled to 1080p, the difference is minor. I’ll watch a blu ray, but I’m not replacing my collection with new videos. Plus blu rays are far larger digital files, a DVD can be compressed to 1.5GB or so.
