How to increase quality of jpg's - HELP

[Brenda]

I am a volunteer for a national charity. Right now, the charity has MS
Power Point presentations on cd that they want turned into DVDs that can be
played either on anyone's television or anyone's computer.

I did some playing around with the Power Point presentation this afternoon
and have 25 jpg's saved onto my hard drive. I put them into MS Movie Maker
(my first attempt at using MS Movie Maker) and realize I have a lot to learn
yet, but that it seems to be fairly easy to use.

I thought all was going well until I saved the project and then played it
full screen on my monitor. The pictures that looked great as small jpg's
are blurry and not the quality one would be proud of when viewing full
screen, so I would hate to see what they might look like on an even larger
television.

Is there any way to increase the quality of the images that were given to
me, or do I need to contact the headquarters and ask them to re-shoot the
pictures using a higher quality digital camera with more pixels?

Thank you for all help, tips, etc.

you can't effectively improve the quality of the pictures you already have,
but you can ask for higher quality ones....

what quality are the ones you have?? consider the best standard DVD quality
as being 640x480 pixels. Are yours higher or lower?

Television resolution is very low when compared with your computer monitor.
It seems counter-intuitive but TV resolution does not increase with the TV
screen size. The resolution of a normal TV (not HDTV) is roughly 640x480,
whether the screen size is 15 inches or 50 inches. It is the size of the
pixels (dots) that are made larger to fill up the extra space on the large
TV screen. If for example your monitor resolution is 1280x1024 it has the
equivelent display area of about 4 TV screens. An image/video sized for DVD
has to have pixels added somehow in order to fill the full screen on that
monitor, however the image detail within the video cannot be increased
beyond what it actually is (640x480). Naturally the picture quality is going
to look blurry when it is stretched out to 1280x1024. The same image/video
would look just fine on a TV.

When checking the DVD video quality on the PC, view the video in a window
sized to 640x480 to see approximately what it will look like when seen on a
TV set.
