I'm currently running a combined FE+BE on an Arch Linux box:
$ mythbackend --version
Please attach all output as a file in bug reports.

My capture device is a HDHomeRun.
I've had a lot of random problems with this setup. My plan is to
rebuild the system, and use CentOS 6 (rather than Arch) as my base.
I was never able to figure out where all my probems were coming
from, so I'd like my new install to be as "clean" as possible. But,
I don't want to lose the following:
(1) Recordings - I want them to be "system neutral", sans
commericals. That is, I just want the video files, with the
commercials removed, that I'll manage via MythVideo in the
(2) Recorded shows table - I don't want to re-record anything
that's already been recorded
(3) My MythVideo metadata - I have a decent personal video
collection, and I don't want to have to download cover
art, etc when I move to the new system.
Right now I'm focusing on (1). I'm not sure what the simplest
approach for this is; there's a lot of inconsistent info on the web,
and very little of that info is versioned (i.e. what Myth version do
these instructions apply to?)
The MythTV docs suggest either mytharchive (I don't want to burn to
optical media, so I don't think that's what I want), or
mythtranscode. But do I really need to transcode? My videos aren't
in .nuv format; they are already in mpeg. So I really just need to
have the commericals removed.
Looks like the first step is to create a cutlist for the
commercials. I trust the job mythcommflag did (i.e. don't want to
manually make cut lists). Most things I read online suggest using
mythcommflag --gencutlist. I can't figure out how to do that:
$ mythcommflag --gencutlist
2011-07-17 12:49:23.685 Using runtime prefix = /usr
2011-07-17 12:49:23.685 Using configuration directory = /home/mythtv/.mythtv
2011-07-17 12:49:23.685 Unable to read configuration file mysql.txt
2011-07-17 12:49:23.685 Empty LocalHostName.
2011-07-17 12:49:23.690 New DB connection, total: 1

2011-07-17 12:49:23.714 No program data exists for channel 0 at
I then tried with --skipdb and explicitly setting a filename:
$ mythcommflag --gencutlist --skipdb -f 1501_20110716200000.mpg
2011-07-17 12:51:24.892 Using runtime prefix = /usr
2011-07-17 12:51:24.892 Using configuration directory = /home/mythtv/.mythtv
2011-07-17 12:51:24.892 No program data exists for channel 0 at
No success. Can I run mythcommflag from the CLI? Or do I have to
setup a job within Myth itself to do it?
It there some other easier/more automated way to do what I want?
