Have recorded 1,500+ recordings (mostly TVE and locast) with very few issues these past few months.

Recently (so far just this channel via locast) sometimes (not always) it records only an audio track, no video.

I have used the "Guide" in web UI to "watch" the live stream from time to time, but have not yet caught this issue (maybe it is a locast issue, but I have not caught it happening live yet).

Here is log entries related to most recent issue:

Anyone else seeing this where audio stream records, but there appears to be no video stream?

This is likely an issue with the Locast feed for that channel.

ok, I figured it might be, I will reach out to them, thanks.
