No answer for eight days maybe it needs some more advertisement:

This patch will reduce the number of "-ss does not work"
and "dvd length is wrong" messages by more than 80% ;-)!
It enables indeed precise seeking and retrieves the total
time of the movie almost always correctly (and it can also 
walk your dog).

Please have at least a look at it.
It's now far more advanced than the last version
(perhaps only the doxygen is missing)
