This seems to be an example of retcon. Whilst in the film the planet Abydos was in the Kaliam Galaxy, in the TV series this was changed, and Abydos was said to be the closest planet to Earth (with a stargate), and therefore in the Milky Way.

I imagine that the reason they changed it for the TV series was so that they could have storylines with the Asgard, the Ori and Atlantis, without the teams being able to travel back and forth at will. This is only speculation though so I'll look into it further.

See Differences from the series.

Can SG teams travel to different galaxies without extra power or an 8th chevron?
