I would love to drop the DirecTv but even with a new TV I only get two channels since everything went digital. Has anyone else had a problem receiving digital signals since the change? I like my TV and don't think I can handle getting one-two channels. Do roof-top antennas make a big difference. I live between two decent sized cities that broadcast and I can't get anything in. I am thinking of just switching between the satellite companies regularly to get the good deals.
