Problem of video viewing (walking on one of the two players)

Good evening,
I have to purchase and install "Cross DJ Get in control" (3.3.10 version € 49).
When I mix video clips (MPG), the clips appear either on any of the screens A and B or on one of two screens A or B, however, means much the music.
Idem A sound clip can well arrange on a channel A and 5 minutes later if I redéposser the test on the channel B, this mouline, mouline.
I have the same concern using the integrated sound card and speaker on my laptop and via the UMX-CONTROL PRO.
To see, I installed on my PC VIRTUAL DJ Free V8 and then everything works perfectly, the same clips are displayed and mixed without problems, a shame.
My PC is I5 system W7 32 bit 4GRam
Could you help me to solve this problem
Another question is how to remove it MIXVIBES the huge logo that appears at the center of the video clip
thank you in advance for your assistance
