*confusing* AC3 track confuses trunk audio code

My frontend has a Chaintech AV-710 sound card, and all audio goes from the frontend to my receiver via S/PDIF. Playing non-AC3 and AC3 audio from my MythTV recordings has almost always been flawless.
Since moving to the trunk/0.23 audio code, for the last month or so of The Tonight Show with Conan O'Brien before cancelation, its AC3 track would usually confuse mythfrontend. The issue may be caused by the transition between non-AC3 and AC3 audio in the same recording. Four samples from the last episode are available, each 100MB (about 55 seconds) in length.
*conan.mpg Taken from the middle of the recording. Audio plays properly.
*conan2.mpg Taken from the beginning of the recording. The non-AC3 track from the local-news program preceding Tonight plays correctly; the AC3 track from Tonight does not.
*conan3.mpg Starts a second or two after Tonight begins. Audio plays correctly.
*conan4.mpg Starts just before or after (hard to tell) Tonight begins. Audio does not play correctly.
This issue also exists with other NBC programs, but not consistently as with Tonight; last night's episode of Community does, but previous ones did not. Both recordings are from over-the-air; unfortunately I do not know if other NBC recordings I've seen with the issue were also from OTA as opposed to FireWire?.
