I thing the algorithm to choose the correct audio stream needs tweaking
a little. It's worked fine for me in the UK with all the files I've
tried but I know of a least one other person where it failed to choose
the correct one. I need some additional information to figure out why
its not working.
Could you run mytharchivehelper to get the stream info on the original
mytharchivehelper -i /path/to/original/file streaminfo.xml 0
and email me the resulting file.
Thanks for doing some detective work by the way. I wish everyone would
do the same :-)
