TMPGenc DVD author,(TDA) can import titles from a recorded DVD.
Use that instead of snapping the vobs out of context. There is no hard
correlation between the different Titles and different VOBs on the
disc.

TDA can edit with GOP precision (gives me a cut precision of +/-0.2
seconds).
Unfortunately, it does not produce seamless cuts.

To cut seamless and with frame precision, use TMPGEnc MPEG Editor
(TME) to cut (and join) all clips in each title before using TDA to
author to DVD-Video format. THe authoring produces the folder with all
the files (.IFO .BUP .VOB) that you burn back to DVD.

I think most DVD-recorders encodes the sound to AC-3 (DD 2.0) format
so you need the AC-3 plugin
(also from Pegasys Inc http://www.pegasys-inc.com)
to be able to hear the sound while editing.
