I have a windows xp system with dual princeton lcd 19 inch monitors using a dual head MSI 6200 video card, one output is dvi one vga, have both enabled and am using both as independent screens.

Here is the scan info on my video card

When I use windows mediaplayer 11 to play a standard mpg video clip I can move that clip from one to the other monitor and still view it fine.

But when I use my dvd player software Intervideo WinDVD4, and play a dvd movie and try to drag it over to the right monitor vs left monitor, I see the framing, hear the audio still but get a black picture for the video, I can even hang this half and half between the two monitors, and left side is working right side is black.



Can't figure out what I am doing wrong here, especially since mpg movies in mediaplayer work fine to move screen to screen, but a dvd movie in Intervideo 4 won't allow me to move a dvd that is in play from left to right screen without showing a black image in the window on right side vs full playback on left side.

Any ideas of what I can check or do to possibly fix this?

Is it possible that since the video output is dvd (vs just an mpg) that the right monitor can't display it due to being vga vs dvi? This doesn't make sense to me though because some don't even have dvi output on their computers but I bet they can see dvd movies with this program still.

I tried opening a vob file in windows mediaplayer then moving it back and forth and it worked (same dvd as windvd4) so it might be something within that program itself Intervideo WinDVD4...

First, you are not doing anything wrong as I get the exact same results with WinDVD. And it has nothing to do with DVI or D-Sub. So it may an "undocumented feature" aka: bug in WinDVD. Actually, with WinDVD, the movie can only be displayed on my "primary" monitor (but like you, I see the empty frame on the secondary).

In WMD11 - I get similar but not exactly the same results. Unlike WinDVD, I can play the movie on either monitor (but my card has 2 DVI connectors) - but it does take a few seconds for the display to come in on the second monitor (sound goes on uninterrupted). But if I straddle both monitors (as in your picture) I get the same results as WinDVD - except it might only display the left side and not the right and that seems to be dependent on where I had the full display last.

If you look at your desktop properties for your card's settings, (using my nVidia Control Panel as an example) what "Display Mode" are you using? I have mine set to DualView. You might want to play around with horizontal mode.

I suspect this is not a bug, but a limitation with the codecs used with DVD (possibly copyrighted) material.

Nevertheless, rest assured you are not doing anything wrong, nor is something broken on your end.
