ext/resindvd/resindvdsrc.c: Additional patch for resin fixes time-based seeking in titles that don't start at sector ...

Browse source 
Original commit message from CVS:
* ext/resindvd/resindvdsrc.c:
Additional patch for resin fixes time-based seeking in titles
that don't start at sector 0 in the VTS, and fixes interpretation
of the cell elapsed time, so that it reports the correct time after
the seek completes.
Really fixes #566957.
