Recently installed an antenna in my attic to receive OTA network stations. I'm using a Samsung DTBH260F receiver since my TV doesn't have a built in tuner. The 260F has a toggle switch where I have to choose whether the box outputs the signal as 1080i or 720p. About half my stations are 720p and half are 1080i. It's not really practical to constantly be switching back and forth, so I'm wondering if it would be better to convert the 720p signal to 108i or vice versa?
