I'm posting this in the software and programming forums. I noticed this issue on my three HR20-700s and the HR21-100 after the new NR. But, it could also be a coincidence, and a D* reception/transmission problem.

D*'s MPEG4 HD LiL of KAKE-10 in Wichita, KS has "jerky" video and a horrible lip-sync problem, greater than a second. The video isn't fluid motion, but very briefly pauses at a constant rhythm. It's unwatchable.

The problem is with any video source being broadcast, local, or network, SD or HD.

However, the D* MPEG2 SD feed however is fine, with no problems.

Also, the KAKE-DT OTA signal is prefect. There are no video/audio problems at all, viewing via the HR20s and using the HDTVs ATSC tuners. So, the problem doesn't appear to be on KAKE's end.

The other two stations (KWCH and KSAS) that have MPEG4 HD counterparts are fine.

the problem is the link or hardware used to send the A/V to DTV, just because the ota is clear does not means the link to DTV is working properly. The signal takes a completely different path on it's way to the uplink, probably fiber

Just talked to the CE at KAKE, via phone.

Says that D* uses OTA for capture of this market's DT, not fiber. So, the problem is on D*'s end, since the OTA is fine. The only question now is the problem at the local receive facility or elsewhere in D*'s path.
