DVPEG 2.3 read.me file
----------------------

- delete your old dvpeg.cfg file and re-run vidsetup if you experience
problems or have a much older version of dvpeg.


Vidsetup.exe
------------
The video setup program must be run before you can use dvpeg. It is used to
select and test video modes and make a list of the working modes for dvpeg to
use.
When the program starts up it will detect what type of video card you have
and automatically enter all of the modes for that card in the user list. You
should find the hi-lighted card on the video card that is in your system.
To test a video mode move to the card you want to test (up/down arrows) and
then hit . This will put you onto the upper right window where you can
pick from the list of video modes that that card should support. With the
up/down arrow move to the video mode that you want to test and hit space. You
should see a series of vertical bars that fade in color as they go from left
to right. If you can not see the bars or the image is junk then dvpeg will
not work with that mode.
When you find what card/mode combo's work with your system you can enter it
into the list by hitting when you are in the upper right mode menu.
To delete an item from the list hit enter until you get to the lower right
user list menu. With the up/down arrow move to the mode you want to delete
and hit .
will move you "deeper" into the menu's while will more you
back out. When you are at the video card menu and you hit you will
exit the video setup program.
At this point it will ask you if you want to save the information. If you
have correctly made a list of working modes for your system then hit and
the file dvpeg.cfg will be created for dvpeg to use. It contains the list of
working modes and a few other things (future features).
I hope that this makes sense and is easy to use. There are a lot of features
to work on.


dvpeg286.exe
------------

This is a 286 version of dvpeg. It is slower but otherwise identical to the
386 version.

dvpeg.exe

F1: help (always check this as I update the program more than I do this file)

next time a file is loaded. Use E to view the file instead of ENTER,

settings are saved in the file dvpeg.vu

of memory [main or disk])

Misc. comments

Hitting ESC will immediately exit from viewing a picture.
Hitting any other key will stop the slide show after the current picture
is loaded.


Closing comments

Please do tell me about video problems if you have any.
