My take is that you probably should consider sending it back if you can. The first point in the reveiw below answers your question I think. There are several complaints there. I took the following off the Amazon website UK - apologies to the writer:

This review is from: Samsung DVD-SH893 160GB HDD Recorder - Black (Electronics)
This certainly the biggest disappointment I've ever had when buying a HiTech item.
Although it does (almost but not quite) all the things claimed, the user interface
is so terrible that I get annoyed every time I use it (every day !). I almost wrote
to Samsung to ask if I had a Beta version of the software, but I never did. I can now
at least try and warn others...
The stupidities are too numerous to mention, but here is a shortened list:
**When you have a timer recording set up - it will not start to record if the unit is
still switched ON (is this software from a VHS recorder?). You can record something
and watch something else as well (small mercies!) but the recording (or timer) must
be already running before you press play - or no deal.
**The Marker system is almost unuseable because you have to remember which marker number
corresponds to which recording. Just to make the game more interesting - when you
erase something that is Marked - the other Marker numbers shuffle around !
**The editing system is nightmarish, and you cannot use Markers that you placed during
previous watching. Gone are the days with my Panasonic where I would watch a film,
"Chapter" the adverts - then all the edits were done before writing to DVD. Even if
you know that a film is so many minutes long, there is no way to jump to that point
during the editing process. You have to watch the program run through ( at x64 max )
**You cannot choose the recording speed (SP/LP etc )to HD when you are using the internal
tuner. Also you cannot record to DVD at a different speed than the HD recording !!!
This means that where I always put two films on one single layer DVD in LP, now I can't.
Well that's enough moaning - I hope it puts you off considering this horrible device.
Even though I've only had mine for about 5 months I think I'll treat myself to Christmas
present of another HDD recorder !
