Query: TV tuner works poorly

The TV tuner on this thing doesn't work correctly. I called Samsung to ask for help in scanning and saving TV channels to memory. It will not save any channels from my cable signal. They say I should use a cable box tuner, or VCR tuner, and bypass the TV tuner. They have no fix available. It sounds like a defect to me.Also, changing channels on the TV tuner takes 2.5 seconds to go from channel 2 to channel 3. That makes surfing the channels impossible, and makes the need for storing your favorites necessary (but storing to memory doesn't work, so I am out of luck).Picture quality is quite good.
