Thank you HD!
Here's my HD line up using ATSC tuning:
- 70.2 CNN HD
- 71.1 A&E HD
- 71.2 History HD
- 72.1 HGTV HD
- 72.2 Food HD
- 73.1 National Geographic HD
- 73.2 USA HD
- 88.5 ESPN HD
- 91.4 Universal HD
- 92.3 MHD
- 114.3 ESPN2 HD
Plus the local HD OTA (over the air) broadcast channels. As you can see here, the channels have decimals meaning they are 'direct' broadcast digital channels. You need to auto tune your ATSC tuner to get this channels. Your mileage may vary and this is not permanent programming meaning comcast can change the line up anytime. You may need to rescan the channels to find out more. I am not sure if they are uncompressed or not, but its is on HD.
Enjoy!
