Ok, I also received an LG to replace the Samsung, through DirecTV's Protection Plan. (I had asked for something other than a Samsung because I was afraid that if they weren't sending out 360's, they would send out 160's. Of course D* wouldn't guarantee which box I would get). After having the weekend to try out the LG, I am pleased with it. I sent back the Samsung yesterday. Here's what I like about the LG:
the "surf" menu
discrete codes for my pronto
s-video picture quality for my dvd recorder
Now I wasn't dissatisfied with the Samsung, if it didn't die out on me I still be a happy HD viewer. HD picture quality I think is about even between the two. SD output looks a lot better to me with the LG. OTA reception is about equal for me. I think the only thing I'll miss would be the AV inputs on the Samsung. I used to use it for my dvd player so I could upscale the Avia patterns.
Still, if I had a choice (like if the Samsung was working properly) at this point, I'd probably go with the LG based on my experience and needs.
