HDTV stuff  
So the HDTV cables showed up wednesday last week (a day earlier than they were scheduled, yay!) so we hooked them up and tried watching a couple different things.

After looking through the stuff i had copies of on both DVD and Blu-Ray, we decided to start with 5th Element (i guess this is something of a tradition amongst geeks?) We Jumped straight to the opera scene on the DVD version, then as soon as it was done we went to the Blu-Ray version. When staring closely at the screen i have to admit that i could tell the difference. There were some minor details that stood out a lot better on the Blu-Ray version. However when i wasn't actually concentrating on the details i couldn't really tell the difference. I think this confirms my initial purchasing hypothesis that when the prices are very close i should go with the Blu-Ray, but it's not really worth paying extra for.

Once we were done with the HD vs regular D comparison we tried out the "Motionflow" system, which supposedly combines adjoining identical frames to make up new frames to insert in between, to "upscale" the signal to 60 or 120hz. The results were INCREDIBLY BIZARRE! Especially during the combat scene. It seemed like everyone was moving a lot faster than they usually did, except they clearly weren't since after any given period of time they were still in the exact same place they would have been with Motionflow turned off. A lot of people compare viewing stuff with Motionflow to watching a soap opera, since it's somehow cheaper to shoot soap operas using a higher frame rate than that used for movies and regular tv, since i don't normally watch soap operas i can't really compare, but it certainly was odd. We watched a little more of 5th Element that way just for the oddity, then switched to the "How To Train Your Dragon" Blu-Ray because shelleycat wanted to see what it did to animation (not as bad, but still frickin weird) before she finally let me turn it off :)

I think your conclusion only holds for re-releases of older media - for stuff originally *shot* in HD format it makes a bigger difference. Or CG stuff that can just be generated in the right resolution, like games.

Actually, wait... I'm sure that applies for old TV, where the original signal is plain SD and the only thing they could do is upscale it. Old movies obviously have more resolution than TV, but I don't know how it compares to 1080 resolution. I think it's gonna depend on how the BR version was created and what raw source they had to work with. So it may actually vary a lot between prints/companies, and I think this actually jibes with vague things I've heard from AV connoisseurs... I'm sure a quick perusal to any home theater nerd message board could confirm that some stuff "ported" to BR looks way better than others.

Agree with this. Stuff that is originally shot in HD is hugely different from the stuff that was later ported. The difference in resolution on an HDTV is astounding between SD and 1080p definition. So much so that I don't ever want to go back to SD resolutions.

I'm pretty sure that stuff that was originally shot on actual film has effectively infinite resolution (well, down to the grain of the film itself, which is definitely "smaller" than 1080p) so as long as they can go back to the original it doesn't really matter.

Hmmm, a quick search on blu-ray vs dvd comparisons turned up this: "and it certainly is worth going to the trouble and expense since the Remastered 5th Element is a SUPERB Blu Ray Demo Disk .. I use the ' Diva Sings ' Segment to demo my system."

(And according to the notes on that page i've got the remastered version.) So if i can't tell that much difference between a normal DVD and the blu-ray in the "superb" case it really doesn't seem like that big a deal.

Interesting. For a second I was gonna say that some BD transfers just aren't that good, but if you're looking at someone else's benchmark, I dunno. *shrug* Though you might also try it with a good animation transfer... I *know* I could see more stuff in the BR version of Bubblegum Crisis, for example.
