I'm not sure why, but it seems like either in the export key frames or in the import process that many additional frames were added at the end of each animation set. In excess of maybe 100 frames were added to each animation set I imported. Not too sure why though!
Sounds like just one of the normal exchange problems with models. I would say to make sure you only have keyframes as some animation files also include b-frames and MDL files are meant to contain only keyframes. 100 keyframes per set seems high real for me inside a real-time interpolation engine, I would think 25 would be good. Of course it goes without saying any added bad frames must be deleted.
The idea of a 2GB model blows my mind.
