Here is the mythfrontend log with the additional logging. One hint is that this log is using a intel motherboard videocard, but I have another frontend that uses an nvidia video card and the both behave the same way. (used pastebin as this kept bouncing off the list for being too big)<br>

Hi Dan,<br>

2013-04-28 13:33:03.765665 E [2698/2894] Decoder<br>
DVD/dvdringbuffer.cpp:521 (safe_read) - DVDRB: Failed to read block:<br>
Error reading NAV packet.<br>
<br>
<br>
This error seems to indicate that there was an issue with the data<br>
from the image. The library MythTV uses (libdvdnav) to parse the<br>
DVD data is reporting that a data structure it was expecting wasn't<br>
found (or was corrupt). One reason for this could be using<br>
encrypted ISOs in storage groups across the network, but you said<br>
your images were all decrypted so unless one has slipped through the<br>
net, it shouldn't be that.<br>
<br>
If the data has been corrupted, it poses the question why the image<br>
plays in other applications (to my knowledge, most use the same<br>
library, although possibly with their own modifications). One<br>
reason may be that some applications attempt to skip the menu and<br>
jump straight to the main feature. That could well mean that<br>
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<br>
--loglevel=debug'. That will certainly give more data (although not<br>
from libdvdnav).<br>
<br>
Are you getting the same problem from the other images that won't play?<br>
<br>

For anyone else having tthe problem of some dvd ISOs not playing in<br>
myth, but working in other players I was able to fix it and keep the iso<br>
format. What I finally figured out is that you can use the program<br>
"dvd-shrink" to re-author the disk (non-compressed) to create a new iso<br>
container. All the movies I was having problems with were fixed by<br>
doing this. Just thought I would pass that along as keeping a single<br>
iso file for a movie is really convenient and I like the myth interface<br>
better than the other players I am using.<br>

<br>
I'm glad you've found a solution but it would be interesting to know exactly why those images didn't play. Did you remove anything (menus, streams etc.) when you ran the images through dvdshrink?<br>
<br>
If you still have an original image, I'd be interested to see the results of running mythfrontend with the parameters I mentioned before. If you run it from a command-line, there may be some additional messages from libdvdnav that don't get routed into the normal MythTV logging.<div>
