[mythtv-users] Somewhat OT: Myth2iPod Transcode Succeeds but Won't Sync

[Douglas Wagner]

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.

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.)

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.

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.

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.
