ACT Guide.
The last two episodes of Kings Cross ER (Gem, 20:30 Thu 20/10 & 27/10) seemed to be repeats, but they're not marked as repeats in the IceGuids. They're not marked as repeats in the yourtv.com.au guide, either, but then that's not showing Friends as repeats, either.
I'm not certain those two episodes are repeats, because the first story in the show was a repeat, so we didn't bother with the . These "real life" shows often recycle material in "new" shows, but not usually as the first story.
