My God! You're totally right! I never thought about the antenna issue. Silly me!
What kind of wire can be used to make an external antenna?
Also, what do you mean about verifying the battery? You mean the remote control one, I guess. If so, I tried to check it to see if it works and it does. The problem seems to be in the mp5 unit, which either doesn't receive the signal, or maybe doesn't do anything about it (maybe very old firmware). I don't know.
Can you make an example of using the remote? If I turn on the MP5, and have a movie start, can you use the vol +/- to raise/lower the volume? Is there any signal of it working, on the display, or the volume just raises/lowers?
