Mixing licenses

[Vlad Stanimir]

I want to create a  video editing program licensed under the new BSD 
license.The program will use a plugin based codec, like mpeg.exe,or 
avi.exe for decoding/encoding  and parsing respectively.Now lets say 
that mpeg.exe is licensed under gpl, and i have another plugin wmv.exe 
with is proprietary licensed. Now mpeg.exe and wmv.exe dont talk to each 
other  but they both talk to Videoeditor.exe and are both  distributed 
in the same installer, wil that be a problem with GPL?
