I'd like to discuss what this change would mean for most MythTV users.

make life easier for most*.

Hi Stuart,

As the contributor of the said method, and also being in the UK, I would
agree that this is 99% of the time the best option, and I've even hacked
it to be my personal default. When it was originally accepted it was the
default, but it received some complaints, due to the cases you mentioned,
and the orignal default was put back.

In particular, often colons are used in show titles eg "American Idol: The
Results", and these programs fall foul of the 's then d' method.

What I think would be useful, is a way of setting default values for new
recordings - this would not be limited to just the dup-method, but also
many of the other settings - recording group, check for duplicates in, etc
