Reprocessing of the Parkes Multibeam Pulsar Survey has resulted in the discovery of two previously unknown pulsars and several as-yet-unconfirmed candidates. One of the new pulsars, PSR J1725-3853, is an isolated 4.79-ms pulsar with a DM of 158.2 pc cm^-3. The other, PSR J1227-6208, has a period of 34.53 ms, a DM of 362.6 pc cm^-3, is in a 6.7 day binary orbit, and was independently detected in an ongoing high-resolution Parkes survey by Thornton et al. and also in independent processing by Einstein@Home volunteers. These pulsars were likley missed in earlier processing efforts due to their high DMs and short periods. These serendipitous discoveries suggest that further pulsars are awaiting discovery in the multibeam survey data.
