[mythtv-users] Damaged Recordings

[Thor]

Hi,
I noticed that recently all my HD recordings (from onboard DVB-C card)  
appear "damaged".
The video itself seems fine, but they are tagged "Damaged" on mythweb,  
and show with yellow font on my kodi frontends.
I am not sure where to start the "debugging". any hints appreciated.
this is from a test recording today :
