That setting only functions with the specific commflag and
transcode<br>
tasks. If you want it to work with your custom transcoding
task, you<br>
must replace the command for mythtranscode in mythtv-setup.<br>

I notice the command in setup for transcode is simply,
"Mythtranscode". Do I need put my entire user job command there
complete with the, " --chanid %CHANID% --starttime %STARTTIME%"
parameters that follow the command, or will these be passed
automatically, and only the script file path/name is needed?<br>

<br>
The value 'mythtranscode' is a special key that tells the jobqueue
to run that application with all the command line arguments needed
to make it work. If using anything other than 'mythtranscode', you
must populate whatever arguments you need.<div class="im"><br></div></div></blockquote><div><br>That makes sense. Thanks.<br> <br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<blockquote type="cite">Also, as I stated in my original post, I used your,

you tell me what the line, "flush_commskip = True" Does? Am I
deleting the commercial flags with this? Would changing that to
false fix my problem, or do I need to leave it as true and swap
the transcode command like you said above?<br>
</blockquote>
<br></div>
All that does is flush the stored commercial skip data out of the
recordedmarkup table. That data is keyed off the frame number, so
if your transcoding command cuts out frames, resamples, performs
IVTC or deinterlacing, that data will no longer be valid and should
be deleted.<br>
