AMC, Cartoon Network, some leased access channel, and Style is switching to digital here on 10/20. I watch AMC a lot, as well as GSN which was removed about a year or so ago, so I should probably get a converter box.
GSN went digital over a year ago, which pissed me off because I had to get a cablebox then because it was my absolute favorite channel (besides TWC) and I wanted to keep it... the Cablebox still has it as channel 37, however that's a QAM redirect to 179.
Man, that sucks. I hope Comcast in my area woun't move CNN, CNN Headline News, MSNBC, The Weather Channel, C-SPAN, C-SPAN 2, TBS, TNT, Cartoon Network, ESPN, ESPN2, FSN Midwest, HSN, QVC, and Cable Marketplace Channel 5 (a local genentic weather station that differs from TWC) to the digital tier full time. Of course, it would be alot worse if they dropped the channel off the line-up for good. I also hope they don't drop WEEK (NBC) and WAOE (My Network TV) off the lineup for good. They already removed both the National Geografic Channel and ESPNews off the analog lineup.
