Also, I reverted the widgets back to the default settings, still the video information dialogue is not showing.

That won't help either of your issues.  For black homescreen issue did you do what I said?

I had some squirrely behavior with my setup before and by completely deleting the skin was the only thing that fixed it for me. Like HugoL stated delete both Bingie and the Bingie Mod in the addons folder then try reloading everything from the Bingie repo then reload from zip the Bingie Mod. Are you familiar where to look for the addons folder with a file explorer? you may have to enable hidden folders on your Mac.

I use this Mac for school works, but I also want to use it to watch tv and movies, since it's the only device with big screen that I have.
Also, I already tried deleting the skin, and the other add-ons that came with it, but still the same results.
