libdvdread tries with both cases when accessing a directory.  
For device access it uses an built in UDF (filesystem) parser.

libdvdread: Can't seek to block 256

actually means that the seek call faild, nothing to do with VIDEO_TS.IFO
other than that this is the first file that we try to access.

Search the archives and you'll find that we've gotten bug reports of this
several times already.  It seems to be a kernel/compiler/drive issue.

Switching to ide-scsi seems to cure the problem for many.  Others have
reported success after inserting a CD first.  Recompiling libdvdread
and/or libdvdcss could fix it. 
There is a debug tool on our site also, see
http://www.dtek.chalmers.se/groups/dvd/dist/dvd_test.tar.gz
That should print a bunch of information ablut the drive and disc.
It doesn't use libdvdread or libdvdcss so if that still sees the error
then it's most likely not a bug in them.
