<div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I record as MPEG4, flag commercials, then transcode<br>to MPEG4 to remove commercials. The video paramters
<br>(resolution, bit rate, etc. remain the same).<br><br>The output file doesn't seek properly on playback.<br><br>Does anyone else transcode MPEG4->MPEG4 for commercial<br>removal? Does it work for you? What version of myth
<br>are you using?</blockquote><div><br>I did not have that problem with MythTV 0.16. When I upgraded to MythTV 0.18.1 it also happened to me.<br>I transcode almost everything automatically to MPEG4 and then when I have time I cut the head and tails off the shows that I want to archive (I archive as .NUV and .SQL). That is unfortunately no longer possible.
<br>You can make the file seek again by running mythcommflag on it like you would do with a broken database, but there will still be pixelation effects when you seek and the file will be useless for dsmyth and other applications.
<br>I have written about this earlier but it seems that it is very rare that people use the MPEG4->MPEG4 "transcoding", so I did not get any responses, expect for the tips on fixing the database.<br>But I would really appreciate if somebody is going to look at the problem now.
