I still use mine. When I first got it I to was getting the freezing after watching for awhile. I noticed it gets pretty warm. So I went to Radio Shack and bought a fan that just sits on top of it and blows air into it. After that no problems, no blue screen, channels come right in, even the HD channels. So my conclusions of most of the problems are contributed from heat. Since the cooling situation, no problems what so ever. I thought I would share that bit of info to everyone.
