Unless the mpeg is mostly nothing at all (very little motion, no flames, 
water, sky, textures, ...) then you will find it hard to get down to 
100meg. Don't forget that mpeg2 (probably the format you have...) is 
already compressed. Also don't forget that 1h30 of *audio* at 128kbps 
(normal mp3/ogg quality) will take about 90-100meg. What you are asking 
is pretty unrealistic. You could do it with mplayer or transcode but the 
results will be horrific. For 1h30 mins you will be down to a very small 
size, very low quality and barely discernable audio. Can you really only 
go to 100meg? You might get something reasonable with 300meg if you play 
around enough but otherwise I would say forget it.

ps. more info about the nature of the original could change everything
