Also I think there is this big question wether a GPL DShow filter is considered as a program or as a library. In the second case that means you should be able to use it from other projects than GPL (or GPL compatible). For example Windows Media Player is not allowed. But AFAIK you can't deny this access to different programs while the Filter is installed on the computer...
The GPL doesn't place any restrictions or conditions on use, just on distribution (and re-distribution).
So if I write a DLL and release it under the GPL, and you load it into Media Player on your system, that's fine. But if you write your own Media Player clone, release it under anything other than the GPL, and ship my code linked to it, that's a no-no.
