Thanks for stopping by to leave a comment. Just to let you know, in answer to your question about advice for small businesses, there are several resources for people in your position at the Dragons' Den site, including an online resource for new businesses, although this hasn't been updated recently.
BBC One controller Danny Cohen has written on this blog about research into audience complaints that background music sometimes seems to drown out dialogue. It might answer some of your points - see Is the background music too loud?.
Mike H, bystander1944, and others have asked about the availability of Windfarm Wars in the iPlayer. Generally programmes tend to be available in iPlayer for seven days - there's more information about this at the iPlayer's FAQ Page, which should hopefully answer your questions as to why it's no longer available.
I've spoken to the programme team (who've all really enjoyed the suggestions in the comments for future business nightmares). At the moment there's no confirmation as yet of any plans for a repeat of the series in the near future.
Zac has already mentioned what the first piece of music played in his film is, as requested by Watcher, but for anybody else who's interested, the full tracklisting for The Trouble With Love And Sex is now available on the show's programme page.
If you go to the BBC's Buzz page for The Killing, it links to plenty of bloggers who've explained the plot and attempted to tie up any loose ends - there should be a few answers, and further discussion there.
A quick word of warning - some of the blogs will contain spoilers, so anybody who's not watched the last episode might want to wait until they've finished it before exploring what other bloggers have to say about it.
Also, for those who may have missed it, in the hundreds of comments we've had on this post, Danny's responded to some of the main questions you've asked, and I'm sure will be posting again as and when there's new news to share with you.
This seems like a natural place to close the comments on this post, but if you want to discuss the second series of The Indian Doctor, or Land Girls and Justice, please do head across to Liam's post, and leave a comment.
