Since the cablecos Virtual numbering is arbitrary, you should probably check your local area forum and do a search for QAM, numbering, mapping, channels, etc. You might have to sort through posts that mention specific channels.
A list will only be valid until the operator shuffles their lineup. They can move channels around without affecting the virtual numbers that the cable boxes and cablecard equipped TVs use, but it will change constantly for some DVR users. That's why VOD (if you can see it) will feature videos jumping around as your neighbors control it. It will stay on the same virtual channel for them but it will change constantly for you.
