I am producing a 2 hour multi-media show with video throughout the show. The video is displayed on projector screens. We use DVD players for the show as we have found these to be the most reliable, durable, and inexpensive to replace if stolen. We have been using a remote control to que the videos, but do not have a way to monitor the video other than what is output on the screen (this is what the audience is seeing). I have been looking for a cheap way to monitor the video before it goes to the LCD projector while on stage. I have looked at portable 7" screen DVD players. This looks like it will work as most of them do have a video out. My question is; If the video signal is sent to some other source will the portable DVD player still display the image? Or is there still some cheaper way to do what I am trying to do?
