-demuxer lavf shows the following info:

So I'm playing back aid 7:

And even though lavf thinks it's dts, it apparently isn't:

Too many video packets in the buffer: (278 in 33558916 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
AC3/DTS sync failed

and further into the playing:

and so on.
