Useful features spoiled by poor engineering

My first version of this product did not function. The disk drive made a grinding sound reminiscent of roughened drive shaft and did not play. When I connected the AUX OUT the signal was not transferred to the external TV monitor. I notified the sellers who told me I had to take a video of the malfunction and send them the file. Amazon.com does not allow such a transfer and would not allow the file to be sent. The sellers relented and told me they would send a new unit. They said nothing about returning the old unit so they could find the problem. The new unit works, I assume, as intended. If my assumption is wrong, then it doesn't work as intended and is just another faulty unit. The problem is that AUX OUT jack circuit was wired in parallel rather than in series with DVD speaker circuit. As a result when the AUX OUT minipin leading to the external TV is plugged in, the DVD speaker is not cut off. In order to get sound from the external TV to dominate I have to turn its volume up very high and lower the volume of the DVD speaker. As a result, the sound from the TV speakers includes a distinct hum that originates from the DVD speaker. If any of my engineering students engineered such an instrument, the best grade they could hope for would be a D. The present unit should function well enough if used in the car on trips.
