This indicates you actually didn't rip the DVD to harddisk, but using 
either DVD on-the-fly ripping, or access a previously ripped DVD image 
on harddisk. Both modes doesn't support PSU core. You can simply switch
it off on the "transcode" page, but aware that A/V sync issues may come
up, in particular with NTSC movies.

Just that transcode's PSU core mode (which is a very internal name of an
algorithm used internally by transcode to optimize A/V sync with NTCS 
movies) is available only for VOB files copied to harddisk ;)

You find more details about this in the dvd::rip online documentation. 
Here are some pointers to this topic:

  http://www.exit1.org/dvdrip/doc/concepts.cipp#concept_psu_core
  http://www.exit1.org/dvdrip/doc/concepts.cipp#concept_rip_mode

In general it's recommended to copy the DVD to harddisk with dvd::rip, 
that's the default ripping mode.
