Is there a software download, preferably free or trial version, that
can allow a typical DVD drive on my computer to function as a
progressive scan DVD.  I imagine it could read ahead, store a portion
in memory, or maybe store the whole disk, anyway, let me know if this
needs clarification.  Thanks

Your computer already functions as a progressive scan DVD when you
view the output through your computer monitor or another compatible
progressive scan display.

However, you do need a DVD decoder.  Popular software decoders include:

"PowerDVD
WinDVD
Cinemaster DVD
TheaterTek DVD"

"Progressive Scan DVD requires high-frequency display, such as today's
direct view and rear projection HD-Ready TV, Computer Monitor, Plasma
Flat TV, or Front Projector.  The signal cannot be displayed on older
analog interlaced sets."

"The introduction of Digital/High-Definition TV brings the progressive
scan technology which has been used in computer monitors for years."

Progressive scanning is a method for representing moving images on a
display screen, where every pixel is represented in each frame. This
is in contrast to the interlacing used in traditional television
systems (progressive-scanning devices are sometimes referred to as
non-interlaced).

Progressive scan is used in computer monitors.  Usually video monitors
use a raster scan to order the placement of pixels of the frame of
video from left to right and from top to bottom at a given frame rate
(e.g. every 1/60 of a second)."
