A/V sync issues

Hi, I am fairly new to the DVD::rip program.  I have tinkered with it 
for a while, and most movies are ripping properly.  But, I have a 
Polaroid DVD recorder, that has a harddrive.  To get the movies to my 
computer I need to burn the movie to DVD, and then rip it to the 
computer.  But I am getting A/V sync problems, like a whole minutes or 
two offset.  Yes its NTSC, and I need to deinterlace.  I have tried 
using the PSU core.  I am going to try again after I leave this message. 
I believe that the Polaroid's audio is mpeg1 and due to not being able 
to just pass it through, there is a offset.  I don't know how to correct 
this. 

I have just started reading the mailing list's archives.  I did not see 
anything yet that would help me.  I guess I should search transcode's 
help documentation.....
