As always ;) : execute the command line above on a console and check 
transcode's output. This might be an NPTL issue, so try enabling / 
disabling dvd::rip's "Workaround transcode NPTL bugs" switch in the 
Preferences.

If that all doesn't work, the current dvd::rip CVS version has

  a) an improved NPTL workarounding
  b) an alternate "slow" frame grabbing mechanism, which is slow
     but bullet-proof

  Building dvd::rip by hand is really easy, once you have installed
  a binary package "fixing" all the dependencies ;)
