screencapping help, DivX, psp7 + 8

I need some serious help. I'm trying to take a screencapture from DivX to psp7, but something weird happens. Like, it takes the screenshot, but I dunno, hard to explain, but it like doesn't keep a still cap, like, wherever the window to divX is placed, I can only see the shot from there, like I can move the pictures window on PSP around and the image thats suppose to be there is staying in one spot because thats the same place DivX is placed also if the window is placed to a spit where DivX isn't there (like lets say DivX is placed on the left upper corner of the screen and the window to the picture is placed on the bottom corner of the screen) it just shows black. Uhh, I hope you understand that, cause it is really hard to explain. But, any idea whats going on? I mean, if I save it when I place the window over the image it still does the same thing once I open it no matter what file I put it under. Also does the same for printscreen. The same thing also seems to be happening on winamp on WMP, but I can't open this movie file on either of those, DivX only seems to work. BTW, I don't have any cool-sounding program like WinDVD or something, just WMP, DivX, winamp, windows movie maker, and psp.

So, please help?
