I have a friend who has one. The DVR is OK. Although it has 2 tuners for some reason when you record a HD signal, the other tuner can only watch something in standard quality. Not sure if you can record two things at once. I would check on that. In my opinion the DVR isnt good enough to pay the premium for it. Just get the cable company DVR for a few bucks a month.
As far as picture quality i dont think the LG is half as good as my Panasonic 50".
