If you have a 1080P tv, the picture of a blu-ray disc is far superior to standard dvd. The picture is so clear, that some movies have to be "dumbed" down as to not appear fake.
I got a great deal at a Circuit City closing on mine. Its great, its an LG BD300 with BD-Live and can stream Netflix and You Tube for $175 with a 3 year replacement plan.
Okay you got a 3 year replacement plan from a store that closed it's doors permanently. That replacement plan is officially useless. I think you've been had.
No, all Circuit City Replacement Plans are covered by an outside company. I verified that before I purchased it. So they are still good, just as long as you don't lose the paperwork. In fact most of these replacement plans stores sell are vetted by outside companies. Learn the system, knowledge is power.
