After clicking the "next" button 3 times, I still can't get to the next page. Is that just me, or is their site broken?

Same problem here. Splitting articles up into pieces to generate page views is bad enough when done competently.

It's not just you. I found updating the page number to 3 will actually bring you to the second page.

I already tried Mobo player and it didn't work for me. I was careful to get the version (of the 3 in the market) that was appropriate for the ARM in the Fire. It just didn't work. All videos I tried played at something like 8x with no audio.
