Launch Base Beta Test

[Blade]

Basically, the program needs to extract all the movies from both the allied and soviet CD's and then rename them all to end in x rather than e. The exception to this is the start movie a00_f00e.bik which needs to be left alone so it overrides the YR one. Instead its the YR one that needs to be extracted and renamed. Ideally it would build a new ecache mix file containing the movies too, but that will need the DCoder mix library. If it can't find the files it should abort and clean up, no point only having some of the movie files and not others. Perhaps return the error to the user saying it failed to find the files it needed and to insert the correct CD and try again and tell them that the mod requiring the plugin will not feature some videos.
