Anyone have HDHR Extend and have trouble with Channel 30.1 ION TV in Los Angeles?

Won’t play live (skips and stutters). Recordings are the same - even tried downloading the recorded file from Plex to my hard Mac’s hard drive and playing it through VLC - still stutters. Can view it just fine through the HD HomeRun app on my Mac.

Signal strength is fine:

Virtual Channel	none
Frequency	617.000 MHz
Program Number	3
Modulation Lock	8vsb
Signal Strength	95%
Signal Quality	90%
Symbol Quality	100%
Transcode Profile	heavy
Streaming Rate	12.149 Mbps
Resource Lock	192.168.1.3

Not sure were to begin debugging this. It works if I set the transcoding to “original format” so the Extend does no transcoding and get an MPEG2 TS, it works fine. But if I have the Extend do any transcoding Plex seems to botch it. I get 180+ channels about 25 of which I watch, and this is the only one.

Any ideas?
