I notice that if I limit DVD's of home video to 1 hour, the quality is
considerably cleaner. The graininess that shows up in certain areas at times
in the longer DVD - basically go away. Some people might not even notice the
difference but I do.

So why is it a commercial DVD can contain a complete movie plus whiz bang
graphics and "extras" and still look very sharp, even on a computer monitor
which I find generally has fuzzier resolution than a TV? Or even one of
these "squeezed" DVD's on a CD with a full length movie can still look very
good, with obviously far less data?

Is it that the master they're working from is so much sharper it can take
more degradation, or the process they use to compress the video, or...?
