File monitoring and comskip are a PAIN to setup. Lots of reading/research/setup/trial & error. But once it is set, it never breaks (see closing note).
The original recordings do not get edited or damaged whatsoever.
Once you have gone comskip, you never go back. It is the main reason I have not turned in my whole house PC based Tv DVR system for a consumer solution. I get the "smoking deal" letters from Comcast weekly to switch to their X1, and I actually liked Tivo when I had it previously. The deal breaker is always commercial skipping.
NOTE: Just two days ago, I noticed my shows were not skipping commercials. Didn't take me long to figure out what was wrong... After more than a full year of running Win10, suddenly Windows Defender decided that comskip.exe was a VIRUS and had quarantined it ? All fixed up!
