from what ive seen HD on demand looks alot better then standard DVD, and BD looks better then HD on demand.
I am only using a 34 inch 720p TV set.
I did watch a HD movie on demand/PPV that I owned and watched on standard super bit dvd, and I was able to see a decent diffrents in picture quality.
maybe it was just the movie you watched, im not sure.
What do you guys think about the difference in bitrate and compression between all the different products calling themselves "HD". Does it make enough of a difference to matter? Can heavily compressed 4-6 Mbps On Demand or downloadable movies REALLY compare with the 40Mbps high def disc versions? Or is good enough, good enough?
I have rented a few "HD" rentals from the x-box live marketplace and a few On-Demand movies from Comcast and I have not been impressed (hence why I hesitate to call them "HD" as many of my SD DVD's upscale to a better looking picture than these rentals). None of it compares to the physical HD media I have seen. Of course I have also seen less than stellar Blu-ray discs as well but their issues resulted not so much from over compression, but from sloppy transfers (presumably to get the product out the door as quickly as possible).
Maybe I just haven;t seen an astounding HD rental or on-demand stream yet, but my gut tells me the compression necessary to get the file size that small has got to result in a hit in quality.
