Don't take any of this the wrong way as I realize you are just reporting what you are getting/seeing, however, just to clarify some things that "relate" to your report for clarity's sake.
If you're interested about WCPO-DT's "jaggies"(probably more appropriately called a "staircase pattern") See Dr1394's posts and his attached graphics earlier in this thread, and our discussion concerning what he found concerning WCPO-DT's "HD" in this thread.
That's great that your mits was ISF calibrated, and that you can't see any "jaggies". But, unless they fixed in since Sunday night it's not changing the fact that WCPO-DT is not even actually sending "true" HD to anyone, and the "jaggies" are one visable indication of that. It's 1280x360 "actual" resolution during ABC HD at least, and that isn't HD. If you do a direct comparison with another source of ABC HD, such as WKEF-DT Dayton or WSYX-DT columbus both which are actually sending "true" 1280x720 ABC HD -- I think you'll likely see the difference ...
It's in their BITSTREAM during ABC HD, the same datastream they send to TW and Insight and OTA. ABC HD feed is being downsampled at WCPO-DT for some reason to 1280x360 before their encoder is sending it out, effectively as "line doubled" or "upconverted" to 1280x720. 1280x360 is as much "effective" resolution anyone is getting during ABC HD. From what it looks like here anyway, it doesn't seem to be happening during their SD upconverts(local programming/etc).
Also, keep in mind --- Just because your DTC-100, and my DTC-100 is working fine with PSIP, and, just because most other receivers seem to be working with the area stations' PSIP currently, it doesn't mean that either/or : a.). Stations have their PSIP tables set up 100% correctly, if not it might effect certian receivers but not others, or : B.) Certian receivers may have PSIP implementation/software/firmware issues.
