Hi Paul,<br>I'm trying to set up my system to transcode all my recordings for the same reason (slow frontend). <br>Sorry I don't have any input on your particular issue, but I was hoping you might give me a tip. What video size are you using? I just tried to transcode a recording (manually from the "watch recordings" screen), and it chugged away for a while, but didn't seem to do anything. The video was still in HD. I'm thinking that after the transcode, the resultant video did not show up in the "watch recordings" screen. How can you get to transcoded recordings, is there something special you have to do to get them added to the list?<br>
<br>I welcome your input and will gladly help you if I can somehow once I get up and running. I also use the HDHomerun, so it sounds like we have a fairly similar setup.<br><font color="#888888"><br>Jason</font><div><div>

<br>
Recently I've noticed two occasions where I've transcoded a recording<br>
from my HDHomerun and the resultant file has very choppy playback. I<br>
have my backend setup to transcode all HD recordings because only one<br>
of my frontend's has the horsepower to play the HD streams as they<br>
are. Typically this seems to work but twice now I've noticed that the<br>
resultant file's playback is very choppy. In both cases I did not<br>
view the pre-transcoded file so I can't say if it had the same problem<br>
or if the transcoding caused it. The choppiness is also very odd,<br>
when I first start the show, the video seems to be slowed down and out<br>
of sync relative the audio. Then after ~10-15 seconds the audio gets<br>
very choppy. If I stop, fast-forward, or rewind the audio choppiness<br>
goes away for about 15 seconds before starting up again. If I try a<br>
different recording it works fine so it must be something about that<br>
particular recording.<br>
<br>
I am recording OTA HD but I don't think this is a transmission quality<br>
issue, this station is very strong and the picture looks perfect. I<br>
also don't think this is a frontend horsepower issue because I have<br>
experienced it on my P4 3.2GHz front end (that non-transcoded HD plays<br>
fine on). Here are some stats:<br>
<br>
Gentoo Linux (updated recently)<br>
mythtv v0.21_p17100<br>
Linux v2.6.16-gentoo-r7<br>
<br>
I'll try updating to a more recent fixes patch this weekend, does<br>
anyone know of an other possible cause?<br>
Thanks!<br>
Paul<br>
