Hi all,, That is Best Buy Brand Insignia,, nothing wrong with it. I have had all the best small DVD players, and I had to connect them ALL to external speakers for volume. Even external speakers you can't buy cheap,, you have to get one with lots of watts. All of my Ipads all have external speakers.. And for the most part they all have rumbling noises while playing some are quieter than others. I ate lunch in my car a lot at work for 16 years.. Yea I am some what the expert at this,, a movie in your hooked up to its speakers is dog heaven. I am thinking about buying this just because it has a 10 in screen.
