Mail Advert Video Player Teardown and Tinker!

I was crawling through my local thrift store and lookie what I found. It's one of those ad video players companies send to potential business partners! I've seen these online but this is the first one I've come across in the wild so I just had to have it. Let's give it a quick demo and then tear it apart to see if we can hack it!
