Same issue with the Wii U browser, but if you set it to Chrome, it works okay.
Why on earth would you want to browse the internet on your Wii U?
Same reason if I wanted to browse the Internet on my tablet, except the Wii U's browser is smoother and more reliable than any tablet browser I've used.
The Wii U browser is the best way to view internet video (HTML5 in particular), such as Giant Bomb HD, on a TV. It also supports live Twitch and you can access the Giant Bomb chatroom though it. Overall, the Wii U GamePad and its browser make for the perfect couch buddy. It's more reliable than having a Tablet, that's dependent on wi-fi.
@shtinky: Technically, the Bombcast is the flagship of Giant Bomb. I get your frustration, but even though I couldn't watch it this weekend after I missed my chance to just download it, I knew that there'd be a good reason and it sounds like there totally was. Stuff happens. They're a small staff. Give them a break.
In Giant Bomb we trust.
What was the reason? Because according to wemiblelec90, the issue was resolved by merely shifting the audio (after a certain point, according to fodigga).
