RE: Problem with movie in presentation mode

This is Chris -- I am trying to help Lisa.
She has an ATI Mobility 9700/9600 run by driver version 7.14.10.830. It has
a pool of 287MB total video memory with 32MB dedicated.
She is on Windows Vista Ultimate OS. There isn't an ATI Control Panel to
change displays and Windows Vista 'Display Settings' only recognizes a
primary monitor while a second display is plugged-in (The 2 is grayed out)
and only gives the option to allow the mirroring monitor to be an Extended
Desktop (not a primary display even while extending is checked).
ATI does not offer any updated drivers on RADEON Mobility cards & the laptop
Manufacturer (HP) does not offer a driver solution for Windows Vista,
although the driver included with Vista was more recent (8/21/2006) than the
driver version update for XP on HP's site (2005).
This driver does not offer the option to change Graphics Hardware
Acceleration and I made sure that the 'Use hardware graphics acceleration'
box in PowerPoint was unchecked.
To simulate the presentation environment, I used a 17" HP LCD External
Monitor as a secondary mirroring display. I made sure the file was in the
same location as when Lisa was presenting and strangely enough the video
played back on both the Laptop Display and the External Monitor.
I'm not sure if the model environment correctly represented the actual
environment -- i.e. if the video out from an LCD Monitor is different than
the video out on an LCD Projector.
You have all been very helpful to me coming up with ideas to try and I thank
you for the support. Hopefully Lisa's embedded video will work tomorrow as it
did in the simulation! If you have any more suggestions please let Lisa & me
know.

Depending on your video card manufacturer there will be different ways to.
access the display controls, if you have nVidia card for example, the process
is different than if you have ATI or Intel Extreme graphics card...
but- the basic answer is:
you need to change the Primary display for the laptop. Currently the Primary
display is your local LCD screen, the Secondary is your external connetion.
Switch that and you will get video on the outboard, and the black box on the
local screen.
Another way to fix this is to try a different compression codec. I wish I
could give you one that guaratees 100% operation, but you will just have to
expirament. Many laptop graphics cards are not powerful enough to display
video on both screens at once, and sometimes an easier codec to process will
fix it.
Hope this helps! If you let me know what kind of graphics card you have, I
can possibly give more specific instructions on how to fix!!

I do a lot of speaking and have just started adding movie clips to my
presentations. I have been editing the video clips with windows movie maker.
Now I've had this problem both with XP/Office 2003 and Vista/Office 2007.
The clip plays just fine on my computer during the presentation, but on the
projected screen there is just a black box. The rest of the presentation is
fine. This has happened at different conferences with different projectors.
I've wondered if it had anything to do with how I saved the video clip (there
are so many choices and I don't really know what I'm doing). Tech support at
the conferences have been stymied, and my colleagues have not had this
problem. One colleague says there may be a setting "buried deep the
computer" that allows the movie to project in both places at once. ??? I need
help-- I'm leaving tomorrow for another conference and need to solve this
quickly!
