Seems to me that I've read that DVDs are 720x480. And, that their information is stored in interlaced format.


Unless I've got these two pieces of information wrong, it seems like DVD would either be capable of producing 720x960 resolution (since even and odd frames could be stored consecutively). Or is it the case that information is actually stored as 720x240 pixel panels where two frames are assembled to get the 480 lined final image?


Whazzzzzup?

Yes each field is 720x240 for 720x480 per frame total not 720x960. But MPG2 encoding is more complex, since most movies are 24fps film-based they are actually stored usually as progressive frame sequences (720x480 per frame) and flags are used to extract and create the interlaced fields as needed.
