In a prior release I modified the service code in an attempt to make the applications more battery friendly, but I inadvertently changed the way playback state was persisted to the disk. This was a major bug, that resulted in the playstate not being saved at the appropriate times, so when you restarted a podcast, you rarely actually started where you left off! This should now be fixed in the latest market release. All apps have been rolled out as of today. Happy podcatching!
