Are the external speakers being plugged into the same jack as the 
earphones? If not, have you tried a) the speakers in the earphone jack 
and/or b) the earphones in the speaker jack? For that matter, are the 
external speakers stereo or 5.1?

I'm wondering if the videos may have 5.1 (or similar "surround") 
soundtracks with a dedicated "centre" channel for the dialogue, and 
maybe mono voice recordings are also being routed to the same channel. 
Perhaps this is being mixed down correctly, with the centre channel 
added to the left & right channels, for the internal speakers and the 
jack that the external speakers are plugged into (if they're stereo) but 
not for the earphone jack.

Just a thought.
