I assume you mean the LVW-5045 (listed as Â£199.75 on the website) as the LVW-500x series does not feature a hard drive.
I am not familiar with what the Samsung is like, but just be warned that it only writes to DVD-R and DVD-RW media, i.e. DVD+R/RW will not work. DivX support would be useful if you are interested in being able to play DivX content on your TV.
Unfortunately, the Lite-On lacks DivX support. However from my experience as a reviewer of the Lite-On LVW-5045, it is very user-friendly and easy to remove the region lock from (the Samsung can also be deregioned with a remote sequence). I'm not fully sure about the editing features of the Samsung, but can confirm that the Lite-On model allows recordings to be split up and merged, chapter editing and hiding as well as copy to & from DVDs (apart from copy protected titles).
