<div>Ok so I got a chance to try the AtomicParsley, I get what it's doing now. I probably wasn't clear. </div>
<div> </div>
<div>The mythTV show transcodes down to a mp4 file, that mp4 file does in fact get displayed to the podcast and that podcast does in fact download to iTunes. It plays just fine in iTunes so all the underlying meta-data for the mp4 file is properly correct, I ran AtomicParsley using the example given for making the file into a video Podcast, it created the temp file, I added the temp file to the library and it refused to sync that also due to the video being in the wrong format.
</div>
<div> </div>
<div>When I look at Myth2Ipod / nuvExport, particuarly the "debug" run that I did I have a few questions:</div>

</div>
<div> </div>
<div>First, the 1280x720 - This is the origial size of the show as recorded by MythTV...isn't this out of spec for the iPod? Doesn't it do either 320x240 or 640x480 only? Or is that the original size and it's being cut down to 320x176 (just before the h264 vcodec switch)?
</div>
<div> </div>
<div>Is there something in the line above that makes this out of iPod spec? Or is there something I should be setting specifically with AtomicParsley to get iTunes to figure that it's OK to play this on an iPod?</div>

<div>Ok, I kind of need to remediate a few minutes. I just realized last week that I could even do any of this. I'm a computer tech but I know almost nothing about video, codecs, etc.</div>
<div> </div>
<div>To my knowledge I need to be using mp4 (MPEG-4) format to get the ipod to correctly play the files. I'm not sure where h264 comes in, is that a standard format for the video? (I probalby should have posted that i'm recording via a pchdTV3000 card, the recordings are dropped into my video directory in mpg format.)
</div>
<div> </div>
<div>My assumption at this point is that myth2ipod is asking nuvexport to produce a file that is out of the iPod's range of play.</div>
<div> </div>
<div>What I don't understand is how to tell nuvexport to do something differently than it's doing now. I'm not sure where i'd tell myth2ipod to encode in xvid format or what that would do for me. Honestly i'm pretty lost on this whole thing.
</div>
<div> </div>
<div>I'll take a look at AtomicParsley and see if I can get some info from it. Any additional information anyone would like to provide (or a tutorial on some of this transcoding stuff) would be most helpful.</div><span class="sg">
