Can anyone confirm that ABC, FOX, PBS, and WB in Madison are passing true 5.1 for audio?
WBUW and WKOW are 5.1
WHA isn't 5.1
For the rest I don't know
Actually, it varies by individual program as well as local station capability. I've seen DD5.1 on network HD programming but DD2.0 on local programming on WKOW (ABC) and Fox47. On WHA-DT, it varies by program. Last night's Austin City Limits was DD5.1 but some programs are DD2.0. I don't watch WB57 much, but I believe they do pass DD5.1 on some network programs but DD2.0 on local. WISC (CBS) seems to broadcast 5.1 on all programs, although the originating source program material may be 2 channel or even mono. Finally, DD5.1 seems rare or nonexistent on WMTV (NBC). Maybe the Olympics were passed along as 5.1, but I don't recall. Maybe other posters can add more detail.
"True" DD5.1 means what? Where the source program is actually mixed in 5.1 and sent along all the way along the broadcast path?
