I noticed one of my local broadcasters does actually flag a commercial break's starts and endings:
Nov 3 16:48:37 channel 17 (TSR1) event Thu 03.11.2011 16:45-17:26 (VPS: 03.11 16:45) 'Hawaii Five-0' status 4
Nov 3 17:13:38 channel 17 (TSR1) event Thu 03.11.2011 16:45-17:26 (VPS: 03.11 16:45) 'Hawaii Five-0' status 3
Nov 3 17:16:08 channel 17 (TSR1) event Thu 03.11.2011 16:45-17:26 (VPS: 03.11 16:45) 'Hawaii Five-0' status 4
Nov 3 17:32:20 channel 17 (TSR1) event Thu 03.11.2011 17:26-17:35 '(null)' status 4
Nov 3 17:32:20 timer 8 (17 1645-1726 VPS 'Hawaii Five-0~Po'ipu') stop
This looks legit to me, start and endings are always trimmed fine - so the question remains, why the recording does not pause during the commercial break?
I'd love to avoid manual editing if possible.
