We report a revised determination of charmed--D-meson absolute branching fractions based on complete reconstruction of DD-bar events at the psi(3770). Two backgrounds, Cabibbo-suppressed and multi-..pi../sup 0/D decays, are addressed in detail. The first measurement of the decay D/sup 0/..-->..K/sup -/..pi../sup +/..pi../sup 0/..pi../sup 0/ establishes the sensitivity to hitherto unobserved multi-..pi../sup 0/ modes. Removal of both backgrounds reduces the values of our previously reported branching fractions by (21--24)% leaving their ratios largely unchanged. The new values are unable to account fully for a reported deficit in charm production in B-meson decay.
