Added nlme code and a note about positive variance components

The OP's aov call has three random effects; to replicate that with lmer my above code is correct. Your lmer code only has one random effect. Which is correct will depend on the context.

Aaron, I don't think that your lmer code is correct. The OPs aov call is simply a standard repeated-measures design, which one would analyze with lmer as lmer(Y~A*B+(1|subject)). (Though see also this answer for more complicated models that permit estimation of across-Ss effect variance and correlations: stats.stackexchange.com/questions/13166/rs-lmer-cheat-sheet/…)
