internal player vorbis error

Description
I've got several DVD rips that I've encoded with x264+ogg/vorbis (using MeGUI on Windows) that don't play in MythVideo? (using MythTV's internal player), but play fine in mplayer.
Steps to reproduce:
(1) Use MeGUI to encode a video, using Ogg/Vorbis? for audio (2) Try to play the video in MythTV (e.g. via MythVideo?)
The video will not play in Myth, and will generate a lot of vorbis errors, but plays fine in mplayer, without any errors or warnings (see attachments).

We need a sample file. The errors you are seeing come from libavcodec, not myth itself-- it's entirely likely that the version of libav* compiled into the copy of mythtv you have has a bug whereas the version your mplayer is compiled against does not.

I'm unable to find an appropriately licensed (e.g. creative commons) video with which I can replicate this problem.
For what it's worth, the source DVD has Dolby 5.1 audio, and I'm encoding using MeGUI w/ogg vorbis for the audio. What I've found is that if I downmix to stereo (2.0 audio, for the audio encoding portion), the problem goes away. So it appears that it's a problem with Dolby 5.1 ogg encodes.
If anyone can point me to a CC video with Dolby 5.1 audio, I'll see if I can replicate it as per the original bug filing.

Using all internal MeGUI tools, recompressing a video to h264, 6-channel vorbis, and mkv, I am unable to reproduce this on Master. Closing until a sample is provided that exhibits these issues, or lacking that, MeGUI encoder settings that allow me to produce such a sample.
