VobBlanker - Skip vs. Blank questions

[JPowers]

Sorry for the cross-post. No one answered the question in the other forum, so I thought maybe it was a newb question.

I learned from a very basic VobBlanker guide how to just blank PGCs. The guide mentioned leaving the VIDEO_TS.VOB alone. There are never any PGCs listed under this, so I never messed with them.

Today I'm backing up U-571. The entire VIDEO_TS.VOB contains trailers and junk, so I decided to right click and try the skip feature, since there is no option to blank. The next VOB was a picture of a flower, so I just blanked the PGC under it as I normally would.

After processing the movie, I played it with Nero Showtime. The first thing I saw was a cut off, half blacked out picture of that flower. I reprocessed the movie with VobBlanker, but this time I used the skip feature on all the VOBs that I didn't want, rather than blanking out their PGCs. Nero Showtime gave me an error message and wouldn't play the second version I processed. VLC media player gave me no problems, there was no flower, and all menus worked.

Is there anything wrong with the method I used? What is the difference between skip and blank?

One more thing, why does the guide say it's important to check the box by use input folder? I always decrypt on the first hard drive, blank to the second, then shrink back to the first one.

Thanks for the help!
