wimbledon looked pretty much HD to me. i know the CW 12.2 airs with an SD signal, and on my Samsung DLP bigscreen, it displays the type of signal being shown. when i go to 112.1 it said HD, like the 5:30 NBC nighlty news. probably over the weekend they will show some sporting event and will come in HD. The display said HD, but Sprint, you could be correct as well, but from what the CW looks like and what 112.1 looks like, there's a difference. now i know in the evening, Letterman on 114.2 comes in HD, while Leno on 112.1 shows in a non-hd format, i guess that is the SD signal(?).
all i wanted to say was that i catch 114.2 CBS & 112.1 NBC through my suddenlink, and 12.1, 12.2, 12.3 with my antenna. all supposedly HD channels.
