I agree with Dustin... I am quite the home theater buff myself as well as
an active member in the MPEG2 (DVD) manufacturing industry and I can tell
you that resolution certainly has an impact on storage space. Typical movie
rates run somewhere between 4500kbps to 8000kbps and that is for normal
DVDs. The new HD DVDs will require almost double that assuming that they
are going to be recorded around 1080i or 720p. Data needs to be stored for
each line of resolution. I'm not certain if that rule applies to video
games though since it is often times the video chipsets responsibility to
render the resolutions but I would think that the laws of engineering would
still apply. Higher resolutions means more data to process and thus more
space required. I don't have Dragon's Lair for my Xbox so I can't tell one
way or another if the game was programmed in 1080 and then it scales down
the video for lower resolutions or vice versa. It's possible that the game
was written natively in 480p and then using some sort of software based line
doubling and anti-aliasing to blend it all together providing the appearance
of 1080. I suppose only the developers know how this was done. As far as
movies go, better resolution = more space required.
