Channel 532 KCTS-HD Audio/Video Breakup (Split from SD thread)

[57]

Is anyone else seeing the video/audio breakup on Rogers 532? I've recently recorded:

Austin City Limits (Arcade Fire) Sunday, 3AM, Tue 5AM (on both my PVRs)
Austin City Limits - Monday 5AM (Fleet Foxes, Joanna Newsom)
Ask This Old House - Mon 10PM
American Masters (To Kill a Mockingbird) - Tue 1AM & Thus 5:30AM (at 12 minute mark).
Nova Elements - Thursday 12 Midnight Live and 4AM Friday recorded.
Cooks Country/America's Test Kitchen - Saturday
This Old House - Saturday
Essential Pepin - Saturday

The breakup was at exactly the same time on both of my PVRs, so that rules out the PVRs. The breakup was worse on ACL and This Old House/Ask TOH (every minute or so) with American Masters being less frequent - say every 5-10 minutes starting about 12 minutes in.

Saturday I recorded the same programming on 525 without issue (except that on 525 the audio is often improperly encoded DD5.1 with the dialogue out the LF & RF channels - part of the reason I prefer 532.)

I have no such issues on other channels.
