This error seems to indicate that there was an issue with the data from the image. The library MythTV uses (libdvdnav) to parse the DVD data is reporting that a data structure it was expecting wasn't found (or was corrupt). One reason for this could be using encrypted ISOs in storage groups across the network, but you said your images were all decrypted so unless one has slipped through the net, it shouldn't be that.<br>
<br>
If the data has been corrupted, it poses the question why the image plays in other applications (to my knowledge, most use the same library, although possibly with their own modifications). One reason may be that some applications attempt to skip the menu and jump straight to the main feature. That could well mean that they're not seeing the corrupted data if it's part of the menu.<br>
<br>
You could try starting the frontend with '-v playback --loglevel=debug'. That will certainly give more data (although not from libdvdnav).<br>
<br>
Are you getting the same problem from the other images that won't play?<span class="HOEnZb"><font color="#888888"><br>

What I finally figured out is that you can use the program "dvd-shrink" to re-author the disk (non-compressed) to create a new iso container. All the movies I was having problems with were fixed by doing this. Just thought I would pass that along as keeping a single iso file for a movie is really convenient and I like the myth interface better than the other players I am using.<br>
