I'm full aware of those terms because I use them myself but I don't think they should be used regarding the translation of ffdshow when you are making the translation accessible to everyone and not just to the more pc expert (like us who are browsing and posting in these forums), it's just my opinion. Anyway eventually the translation will be completed and you guys can give an opinion about it... or not!
P.S.=> Looks like there are more Portuguese speaking people here than I imagined after all!
Fiquem bem!
