The TrackMania Forums offer the release of new updates for TrackMania Forever which fix a few bugs. This page has details on the new versions, where they say: "There is a notable change being that the binks in manialinks and mediatracker images now work with transparency." There is a patch for TrackMania Nations Forever and TrackMania United Forever, and word is: "this update which should be compulsory in a few days." This forum post also offers the corresponding dedicated server. Thanks Frans.
