Abstract: We present a measurement of the branching fractions of the 22 decay channelsof the B0 and B+ mesons to Dbar*D*K, where the D* and Dbar* mesons arefully reconstructed. Summing the 10 neutral modes and the 12 charged modes, thebranching fractions are found to be BB0 -> Dbar*D*K = 3.68 +- 0.10 +-0.24% and BB+ -> Dbar*D*K = 4.05 +- 0.11 +- 0.28%, where the firstuncertainties are statistical and the second systematic. The results are basedon 429 fb^-1 of data containing 471.10^6 BBbar pairs collected at the Y4Sresonance with the BaBar detector at the SLAC National Accelerator Laboratory.
