If you have a HDTV tv, not a HDTV READY set, and you are connecting the DTC to your TV with the HD15 (VGA) connector on the back of the DTC, use the DTC unless your internal TV tuner can pull the channels in better. If you aren't using the HD15 connector, use the internal tuner. It's really up to you which you use in this situation
If you are using a HDTV READY set, you will need to use the DTC to get OTA HDTV
hey there I live in Escondido and I'm getting all the digital channels from both san Diego and LA. Yes you need to plug the antenna into your receiver not the TV. After that make sure you have a good antenna (I have a Channel Master 4228a with a 7775 preamp)point it towards the towers and enjoy http://www.avsforum.com/ubb/smile.gif
For more detailed info do a search on "San Diego" in this forum and the HDTV programming forum. There is a bunch of great info that helped me and it can help you too
