Comment (by riscycdj@…):

 I have the same problem as specified in the original ticket. I couldn't
 work out why some Blu Ray rips were not playing back correctly and others
 were. The only difference is 5.1 downmixing. I am using 0.23+fixes on the
 Mythbuntu distribution. I'm not sure what extra information is required to
 help troubleshoot this issue.

 Here is an extract from mythfrontend.log:
