ok, as a followup to my previous post, i slapped f9 on my inspiron, then VLC and associated RPMs, popped in a DVD, it plays nicely on the laptop.
then, connected an external (samsung WUXGA) flat-panel monitor via DVI, and the entire laptop display is reflected nicely on the monitor *except* for the actual DVD image in the VLC window -- that just shows up as blank, either in regular or fullscreen mode (in fullscreen mode, the entire external display is blank, even while the movie is playing on the laptop).
i'm no expert at video so, somehow, the DVD image is not being passed out on DVI, while everything else is. thoughts? is there a VLC setting to tweak this? this is a dell inspiron 9200 so it's a fairly old system -- at least a couple years. but until now, running external displays off that DVI port has worked just fine. so why is the DVD video content being treated this way?

ok, i just realized what the problem is -- the onboard video simply isn't powerful enough to display the playing movie both on the laptop display and on the external display, so i simply need to disable the laptop display. and one would think this would be easy -- there is a blue "CRT/LCD" on F8, leading me to conclude that a simple Fn/F8 should do it.
sadly, that key combo has no effect. how odd, since it's *exactly* what i want to do -- disable onboard video and drive external video. i will now google, but if someone knows how to get that on an inspiron 9200, i am *so* interested in hearing it.

I thhink that part of the problem is that the laptop is exporting a framebuffer and the DVD image isn't going through that frame buffer. Does the laptop use hardware acceleration?
When I tried to xwd an mplayer image, there was just a single color where the image should have been. Anyone know how to screendump from mplayer without guessing the time or making multiple images?

this is a mobility radeon 9600 M10 chip, and from Xorg.0.log, i read that there is something called "xaa" acceleration (damn, someone just walked off with the laptop). in any event, i think what i want is a utility to deactivate "LVDS" while leaving "DVI-0" active, based on what i read from the X server log file.
aticonfig? something like that, i think.

I do not think it is a problem with vlc. There should be a video overlay issue:

What graphics card and which driver do you have?

ati mobility radeon 9600 M10, and the stock "drm" and "radeon" modules that come with f9. this is a fresh install as of this morning, so i haven't had time to make a mess of it yet.

On an old HP/Compaq EVO 800c with radeon I need to do a:
yum install xvattr xvattr -a XV_SWITCHCRT -v 1
to get video on an external monitor. Then the video is not shown on the laptop. To get it back, do a:
xvattr -a XV_SWITCHCRT -v 0

as i posted earlier, i got pretty much the same effect using "xrandr", but i'm still unclear on what happened underneath. a colleague's explanation went something like, "seen that before ... blah blah blah ... video card ... blah blah blah ... not enough horsepower ... blah blah blah ... can only drive one screen at a time ... yadda yadda yadda."
someone else suggested that the DVD image was bypassing the framebuffer, which i didn't follow. can someone clarify the technical issues behind why i need to deactivate the attached LCD display on the laptop to get DVD output on the external display? i'm convinced it works, and now i know how to do it. i'd just like it to not be quite so much magic. thanks.

I'm not sure about this but I suspect the video display may be using a video overlay surface:
http://en.wikipedia.org/wiki/Video_overlay
Typically you can only have one overlay surface per graphics device, not per screen. As I said I'm not sure if that's what's happening for you but it's a likely possibility.
