I have tried to watch a few missed episodes on Demand 5 but keep getting errors. The breaks don't sync up to the footage of the show and I miss the end of the show due to this and other footage. The ad breaks are also very long. I do not have any ad block software installed to interfere with it.

Is anyone else having problems with it?

I have ABP installed on Firefox and it works fine.

I've watched quite a few CBB episodes on catch up on the PS3, and it works a treat!
4-OD can be a complete nightmare on it though
