closed source windows freeware, so what do you expect? At least, they have really written it themselves, not just ripped some FOSS project (sadly, there is no FOSS project able to recover our videos in such case).

Anyway, wine *is* native. It wouldn't be native, if you would had to emulate something (like, cpu - but of course, I got what you meant, anyway, so mentioning it just for the record).
