Why would that be a problem? Have you not already seen it? Will you not be PVRing it so you can skip the ads? Is the news in the middle of the film (a licence requirement) really that bad?
You missed one out, their picture quality.
BBC, ITV and Ch 4 have HD Channels on terrestrial and Freesat, you can only get Ch 5 HD if you have a Sky HD box paired with a current Sky card.
Factor in that Ch 5's SD quality is very poor too compared to the other main channels via satellite and I tend to hope they don't get any decent films either.
Personally I much prefer to watch a good film in HD on the other Channels recorded on my Freesat PVR.
