The PROBLEM is that the speakers are connected to the DVD player unit so if that's not used you have no speakers.
If you used a different TV box then it sends a video/audio signal up the HDMI input to the TV but there's no path into the DVD unit and thus the speakers.
*The MANUAL describes how to input the video of one other media device into your DVD unit. Once that's setup both devices have to be powered on for this to work.
