Hope you can help!

Been trying to rip the young ones series and altho
i managed to rip 5 of the 6 episodes, the last one
is really giving me hassles.

Not only is the rip not starting at the beginning
correctly, but about 97% into the rip and it
appears smartripper is having trouble gaining
the key to continue. What i end up with is a
rip where the beginning and end (last few seconds)
are missing. I did manage to get the missing end
bit thru 'dvd decrypter' but still no beginning
sequence. I have no idea which vob file it is thats
missing.

Smartripper asks me if i want to 'quit' (after it
starts searching for key)...i say 'NO' and it stops
anyway??????????????

All the other episodes ripped ok with start & end
intact, but this last episode is truly mixed up rotten.

Can anyone by any chance point me in the right direct-
ion to identifying this missing opening section? or at
least how to do it?

Am i right that i can import individual vobs that were
taken from different rippers (using 'add' option in
'dvdtoavi') ???

Mucho Thanx in Advance
