Source for the problem is actually write function (line 242) which
generates log, not CreateDVDISO or BurnDVDISO functions themselves.

If I understood right DVD standard recommends ECMA-6 which is actually
us-ascii character set.

Maybe this fourth option is best(?):
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/251871
Convert unicode characters to closest ascii equivalents.

But if have to choose from these three options, I would go with #2.
After all title encoding is not very important issue. Title of the dvd
is hardly never used. Most important thing is that DVD authoring process
is error free.
