We had Adelphia for the past year,Comcast took the reigns 10 days ago.Ping times have drop on the HSI to the West coast from 110ms to around 75-80ms,INH2 was pulled 2 days ago and TNT-HD was added,there are 3 new channels showing up in the HD area but when you check them it says not available yet. So far the switch has been going great
