Comment 0 for bug 951560

Hi everybody,

I have used Arista Transcoder for the last year to convert the video of my favourites tvshows to my iPod Touch device, but the last week I'm having problems with the transformation, the converted videos can't be played by the ipod touch and are not recognized by the iTunes application as "valid videos for the iPod". This occurs to all mi iPod devices (2nd generation and 3rd generation) I can transfer via SSH but can't be played by the video application. (VLC open's it without a problem)

I am using (during this week) Ubuntu 12.04 precise (development branch) and the version of arista is 0.9.7. I'm trying the default preset for iPod Touch as the new version hosted in the arista homepage (version 1.2 of Daniel) but the result is the same.

I'm comparing the new converted videos versus the old ones (by its metadata and there is some diferentes that can help us to solve this problem).
