Well...there is a free version of CoreAVC, although old. I use it and it works fine for me.
And then of course....you realize where you are...so uh...I'm pretty sure CoreAVC is free 
In the respect of an old version, you may be correct. CoreAVC itself however, is either a 14 day trial or a 15 dollar license subscription. Provided I could easily get it for free through illegitimate means, but I'd personally rather not do that considering how excellent of a product it is. Against my code...(but I will not shell out 15 dollars for it either, since it will not provide much advantage for me anyway, GPU offloading is not really necessary and stock ffdshow decoders, or even the Media Foundation's H 264 codec will result in similar quality)
Before you call me out though, the reason why I don't follow that rule with anime is because I hate how the companies go about it. Not every show is aired on TV, and even if it is, not everyone has the ability to watch it all the time. Does that mean for people to find new anime series they like, they have to gamble on expensive box sets without knowing if the show they are buying is even a good one? I use bakabt for the purpose of finding anime I like, and all of the ones I do like, I subsequently purchase the box sets, to reward quality work. My uploads are strictly for the purpose of pointing out anime I like to other people, and to remind people of the shows the grew up watching in the case of the toonami uploads. If I thought it would help matters, I would put a thick banner in every one of my descriptions saying "If you like this series, THEN BUY IT PLEASE!!!". Unfortunately that would just cause people to skip over my descriptions instead.
