[mythtv-users] Commercial Removal

[Michael Wisniewski]

Mike,

Thanks for the response.  I tried commercial removal a few days ago and it
worked great.  I tried it yesterday and it didn't work at all.

>From how I read the wiki, it sounded like Myth flags the commercials (if
it's checked/selected) and will skip them on playback.  If you want to cut
them from the show, you have to transcode the file.  If you don't transcode
to a different codec, it just cuts the commercials out quickly.

Obviously, it's not working for me, so I'm wondering what I am doing wrong.


Thanks again for the response.  I'm getting the feeling that it may not
automate things as much as I originally had thought...
