Advertisements Guys, I know this is likely a flame-worthy question, but I've done my searching and couldn't come up with a great answer. I've sort of been out of the HD (other than OTA) game for a while, and tonight I was looking around the "dial." I noticed I was getting a White Sox game in HD on ch. 94. I was mildly confused as to why I was getting it (I'm not a MLB or HD package subscriber), but didn't really give it much thought. Now I'm watching some sort of National Geographic programming in HD on 94. Now I'm slightly more curious to find out what this channel is all about. Thanks!
