One of the Comskip users reported a problem with the commercial detection on low resolution recordings.
Low resolution is defined as a recording having a lower horizontal resolution compared to the vertical resolution.
An example is a DVB-T stream recorded at 544*576.
You can check if you have this problem when you set verbose=5 and check the log file for long segments with an aspect ratio of 0.0
The problem has been solved in version 79.15 (comskip79_15.zip) which can be download from the link below.
