Well, what can I say.... it appears the TV can't handle italic formatting <i> tags.
You should report this to LG support, but I don't have any hope of LG fixing this any time soon. They seem to have given up on webos alltogether. They LOVE To sell new tv sets, but fixing these kinds of "basic" issues with their software seems to be very far down on their list of priorities.
I love the new thinking with webos, but I absolutely HATE having anything to do with LG. They really just doesn't seem to give a damn...
