There are a few threads near this region, but nothing specific to Comcast.
I'll get things rolling with a list of clear QAM channels ATM (that I've found).
These are sorted by Comcast channel.
CC = Comcast Channel
MHZ = Carrier Frequency
Channel = QAM Channel. My DVR remaps minor channels, but the major number should be correct for everyone.
