Of course you can - I presume you are aware that recordings are also locked to your specific TV?, you can't even transfer the drive to an identical model.
It's a bit fiddly compared with using a PVR and as there is only one tuner you can't watch one programme and record another. The TV also takes a bit longer to come on as it checks the drive at start up. I found it a waste of time to be honest unless you want to use it to pause live TV which it does quite well. It chopped the end off one programme I recorded so not sure how well it tracks start times.
Ok, just thinking of getting hard drive for recording just need to know if it records the beginning and end and when programme starts late and if records when tv is off, before I get one
it seems that it can do Series Recording but might not track recordings if the broadcast time changes.

Quote: “If the selected programme is part of a series, you can make series recording by selecting [Set Timer As a Series]. (This function is available depending on your region/country.)”
