The time displayed in the OSD is an estimate and it's not always correct 
(some of my 60-minute recordings show as being about 52 minutes long, 
but they're actually about 60 minutes of playback).

Also, the seektable may not be correct during LiveTV or recordings in 
progress.  If you enter playback after the recording finished, you 
should get a valid seektable (again, note that the OSD times are 
estimates).  If you don't, please see

That's the time taken to shut down the old recorder and then start the 
new recorder (including all its initialization, such as changing the 
channel).  Note that this is always done--even for back-to-back 
recordings on the same tuner and same channel.
