I'm sorry to hear that this inconvenience is taking away from your viewing experience.
What's the model number for your Internet@TV device, and how often are you accessing Internet@TV?
There's not a way to disable the updates - since the widgets are updated often, and those updates aren't something you can toggle in the menu.
Every time I access the internet@TV feature it requires and update. it seems to to be updating the same apps picasa web albums and twitter. and it does this EVERY TIME. it is extremely inconvenient and annoying. why does this continue to do this? and how can i possibly put a stop to it?
