ah so thats stuff like apache deflate in action? awesome
Anyway, fixed the movie (or so it seems), luckily the google repository had documentation for version 4 (i see there's no documentation, at least there, for version 5)

Now, don't use TME for snes9x movies until the issue is fixed, it screws up the header's savestate + controller offsets for whatever reason (for snes9x, I haven't had trouble with vba movies for instance). At the very least test your file won't increase in size after saving before trying to use it.
I don't promise I'll fix it so if I dont and this is putting your work on hold, get an hex editor.
The first 4 rows of sixteen values are the header, copy from the start of the file until address 82 (131 bytes = 131 boxes with values) to a new file or something.
Then, looking at the "string" output, find the last instance of "X-MEN", on the hex it will say something like CB 8C 87 AE 58 2D 4D 45 4E. Copy from the start of this (CB 8C ...) until the end of the movie. and paste it on your new file then save. The CB should be at address 83 since address 82 was from the first copy.
Then, starting at address 18 (25th value), replace the values with this 9E 00 00 00 00 03 00 00. Then save, your movie is fixed.
Don't let it grow that huge next time, should have reported the error asap (if you didn't).
