libdvdcss dvdcss_seek() args

[Cliff Tuel]

Greetings from a newbie, using OS X 10.1, with a libdvdcss question.

The sample code on http://www.videolan.org/libdvdcss/sample.html won't
compile with the latest cvs snapshot; a 3rd arg has been added to
dvdcss_seek().  What should this be?  I guessed DVDCSS_SEEK_INI, which sorta
works.  If I change the sample to code to iterate over sectors 0...N, it
eventually bombs out:

libdvdcss debug: GetASF authenticated
libdvdcss debug: already authenticated
libdvdcss debug: requesting AGID 1
libdvdcss debug: drive authentic, using variant 0
libdvdcss debug: authentication established
libdvdcss debug: received session key
libdvdcss debug: GetASF authenticated
libdvdcss debug: already authenticated
libdvdcss debug: disc key won't be decrypted

libdvdcss error: no key but found encrypted block

Program received signal EXC_BAD_ACCESS, Could not access memory.
0x00003620 in CSSDescrambleSector ()

Bonus Question: how to prevent "cracking title key" each time?
