If were going to talk about numbering systems, I'd like to say that I'm looking at D* list on wikipedia, and I think it's a little confusing. For example, you have CNN and HLN on 202 and 204, but the rest of the cable news channels are in the 350s. Also, you have some sports channels in the 200s and others in the 600s (I know some of those are RSNs) But I'm just saying, have all the news channels be together and the sports channels be all together so it can be a bit easier to find what you're looking for.
