At 9:05 PM, Sunday night, channel 163 has a center cut 4:3 of the same program (Wuthering Heights) being shown on PBS-HD. My guess is that the SD version of PBS Detroit is now being created by conversion from the HD signal in preparation for the shutdown of the analog transmitter. The WS version seen previously might have been a setup error in the downconverter that has now been corrected.
DW looks good in 16:9 SD.
BTW, don't assume that SD STBs can react to MPEG aspect ratio flags or pan and scan instructions. It might be in the MPEG chip but not be activated in the box setup software.
