The no-name stuff is about $1 to $1.25 and the 'brand name' (Verbatim)
$2 or so (in the 15-20 disc cakeboxes - the single and 3pack prices
are higher of course).

At least in the US it's (technically) illegal to "rip" a DVD even for
your own use (as a backup) so I'm not overly comfortable with having
a "here's how you make copies of DVDs" session...
No 'recombining' at all. And yes that's where things get messed up.
It's the decode/re-encode process where problems creep in.
Basically what happens is that the result of rip'ing the DVD will
give you a "VIDEO_TS" (and possible a AUDIO_TS directory which is
usually empty) directory containing the .IFO files and the decrypted
.VOB files. BUT NOTE: NO DECODING or ENCODING or mplexing/recombining
is done.
mkisofs has a '-dvd-video' option so you do something like
cd scratch_directory
ls -l
(at this point you should see the VIDEO_TS and AUDIO_TS directory)
mkisofs -dvd-video -o /var/tmp/BIGIMAGEfile.img .
then use the burning software of choice to write the BIGIMAGEfile.img
out to the DL media.
That might pose a problem though for some folks. Maybe not. But the
last time I tried the 'growisofs' and 'cdrecord-ProDVD' tools they
choked on DL media. OS/X doesn't have a problem so I do the DL burning
there (usually with 'Toast').
