editing 2-3 times with DVD Shrink / PGC Demux delay correct?

[efc1978]

Hi,
I have some DVD's I have edited 2-3 times with DVD Shrink as it 'cuts' keeping lossless.
For example as I obtain more footage of a concert months or years after I make a DVD I like to add more of the footage into the DVD, so I have some DVD which have been ripped to my HD and cut with DVD Shrink up tp 2 or 3 times...
My question is, as I know cutting with DVD Shrink changes the audio/video sync, if I open a DVD I've edited with DVD Shrink up to 3 times in PGC Demux, will the audio delay PGC Demux shows still be correct?, is that kind of info still accurate if i've cut with DVD Shrink a few different times?
Will PGC demux show the correct delay time, or is it going to be inaccurate because it's been messed with in DVD Shrink a few times?
Thanks for any help.

If the edited DVDs are in synch, any delays given by PGCDemux will be correct.

Thanks, I wasn't sure if cutting the same part on up to 3 different occasions with DVD Shrink would somehow 'throw away' information and make PGC Demux 'lose track' of what the correct delay should be....
Thanks
