Using Locast out of Baltimore and noticed two things with it...
First, generally the volume on Locast channels is lower than compared to either OTA or TVE. Switching to Locast requires, at least for me, to increase the volume in order to hear well.
Second, WJZDT and WJZDT2 have no audio when watched in either TVOS or IOS. However, watching from the web interface the volume is fine though it is out of sync with the video by 10 secs or so.
Otherwise, looks good including the fix for the sub-channels.
