I am a new customer of Xfinity and am trying to figure out the channel lineup. Am I correct in assuming that the lower numbers are standard definition and the higher numbers are high definition? From looking at the lineup it seems that channels 1-659 are stardard and the ones beginning at 680 are high definition. Some channels are repeated in the low and high numbers so I assume they are just the low and high definition versions of the same channel. If I select one of the low definition channels do I automatically get transferred to the high?

Hello denmarks43, that is correct the lower channels are SD and the upper channels are HD. You can find a channel lineup for your area by clicking on this link.
