All video comes up as a blank screen except in "theater mode" in overlay tab

Okay, this problem is so frustrating...I am using a radeon 8500 128mb AIW

Using the DVI cable to my NEC LCD 1850x

all video in media player (as well as other players) displays only a blank
screen...audio is fine

the preview pane in xp shows the first frame of the video fine.

I can get it to work by selecting "theater mode" in the overlay tab of my
radeon options

and/or I can get it to work by cranking the hardware acceleration down to
the third from the "none" anything above that yields the black screen.

I've tried updating directx, windows media, downloading various codecs, all
sorts of things...

one thing that works is bsplayer...it plays the videos fine however it has
two errors upon openning.

"overlay failed"

and

"Display hardware is not capable of color-space conversions. Switching to
RGB" I click OK and all works

What does it mean that it is "switching to RGB..obviously this has to do
with the colorspace native to the dvi cnx right..

I gave away my dvi to vga adapter already thinking I was getting a better
cnx btwn my pc and my ati card...Should I go back to the vga cable?

Thanks
 
I'm sure I knew at one point what overlay mode was - something to do with
letting the graphics card do more of the work I think - videos in preview
mode use far more CPU time. For some reason my card isn't able to run
overlay video on my second monitor - i.e. if I drag media player across both
windows, the second monitor part is just a blank area while the first
monitor shows it's part of the image fine.

Check that you have set the LCD as your primary monitor. For some reason my
card recognises the monitor plugged into the DVI as monitor 2 by default,
even if there's nothing plugged in to the VGA socket.

Thats likely the reason.

In short: overlay is when data is written directly video memory.
Non-overlay means data has to be transformed into RGB, which btw. is done
by the vpu.
