Trailers in a teeny tiny window
I tried this last night, mainly to see what the quality was like (and whether it's worth paying for). Unfortunately the trailers appear in a small window in the centre of the screen. No option to make it full screen. So it looks like I have to pay to see whether the quality is up to scratch (bah). That is, of course, assuming that if you pay you get to watch the film in fullscreen (who knows!?!).
On the plus side the video didn't freeze (2.5mps connection) and the audio was excellent.
