original dictionaries – where to buy?

Hi,
You can download many dictionaries, but they're many times corrupted – be it wrong encoding or, generally – without audio. As fair use applies to such files in my country, I can use them kind of legally. But I’d like to have full-featured and professionally made ones.
The app such as GoldenDict has changed my life and workflow. Really. Looking up words and phrases has never been easier. But it’s only an interface to dictionaries. But they are scarce…
I’m interested in as many English-English dictionaries as there are out there. Now I have OALD8, Collins Cobuild5 and LDOCE5. But frankly speaking, I do not know where they come from! How one could convert them? I often spent many hours of searching for them. Many of them were of poor quality. I haven’t even been able to find converters!
Where is the problem? Is it publishers who are reluctant to open their formats? It’s ridiculous to have many interfaces – and of course you have to have Windows!
How could I make my dictionaries ‘legal’? I do not want to have half-products – without audio, with corrupted entities and problems with encoding.
What do you suggest?
