Heh, yes someone pointed out to me that it was probably "Everybody
Speaks Nonsenses II - Hot Pot". With all that enthusiasm and
patent nonsense I didn't even try to listen to the words, it
just automatically fell into my internalized Japanese TV category.

Yes, svn trunk is what will probably become 0.22.. It did complain
about A/V sync in the file being way off, but was able to cope.
I believe Janne increased the allowed difference between audio and
video before MythTV will give up on A/V-Sync. There is of course
a trade-off here, the greater the difference in A/V you allow the
longer all operations can take, and the more memory you can
consume.
