I was curious why deep analysis is not used on the first pass as suggested in the manual?  Would it make any difference in quality if you did use it the first pass? I would rather not considering time, but if it did make a difference it would be worth it imo.

Afonic,

thanks for all the help the other day.  Sometimes I got ahead of myself and asked questions here before I fully vetted them myself.  Anyways I successfully created my first miniDVD on 3 disks with two shrinks and it came out great.  Even played on my philips DVD player which was a surprise.

It should make quality better a bit but I don\'t know if it worths the extra time. You have to try and see!

For miniDVD, DVD2One should do a nice job two, as it needs only 1 compression. I suggest you try it, I will probably write a new guide next week.

Exactly.  I found that the quality difference wasn\'t noticeable enough on the first pass to waste the time.  This is only an observation based on my experiences with DVD Shrink.

Well I did my first test between DVD shrink and DVD2one; with Pirates of the Caribbean.  To be honest the quality is very close but if I had to choose one I would say DVD shrink.  The DVD2one copy, the sound cuts in and out the first 6 or 7 seconds then quits, but I only watched about 10 minutes of each.  I might try another movie sometime to see if I can tell any better.

The time involved was definetely on DVD2one\'s side; at least half the time as dvdShrink, but I did do deep analysis on each backup with dvdShrink.  Also on each, I only shrunk down to 2795MB (4 disks) because it would take more than 2 shrinks on DVD shrink to get to 2100mb.

On dvd2one it got alittle tricky and maybe you guys know a better way than what I did.  I wanted to cut out the ending credits in each but I didn\'t see a way to do this with dvd2one.  So instead of using dvd decrypter, I used dvd shrink, cut out the credits, subtitles and sound, and encoded with zero compression.  Opened dvd2one and encoded to 2795 mb and then opened dvdshrink again and split the movie.

Let me know what you guys think, if you have done any tests and all.  Also if I might of missed something in dvd2one, like being able to cut out credits and split the movie.  One last thing, do you think the sound cutting in and out had anything to do with switching back and fourth from dvdshrink and dvd2one?

You did it the right way, the idea is that you can have only two shrinks (one with DVD2One and one with DVD Shrink -basically to chop the video in two) for any movie.
