Colin, mind opening a new bug for that dvd issue? That looks like a crash due to a bad pgc->cell_playback_offset value, which is different from this bug. This one is already closed and considered fixed, so no further work is going to be done on it.
I seem to recall having a similar issue with that disk, but didn't investigate it at the time. You might want to test the upstream libdvdnav/libdvdread, as a lot of fixes have gone into those lately, so there might already be a patch available. If so, and especially if you can help identify which patch is needed, that could help accelerate getting that fix into precise.
