I don't know the tin84 specifically, but the mega164 needs to have the ADC turned off and restarted every sample to get valid readings.

I'm using free-running ADC conversion so this would definitely affect me 
if it is a problem with the Tiny84. There's nothing in the errata, but 
then there isn't for the 164 either.

I'm going to switch to single-ended conversions on each of the two 
channels for now. However the bipolar/differential/free-running mode is 
a natural fit for this application so I would be grateful for any 
further suggestions.

Thanks,
Mark
