vobcopy vs. dvd decrypter?

[shevegen]

Hi

well ok this comparison is not fair
decrypter features GUI and lots more options

anyway, my perception was that it is a LOT faster getting the data
of a dvd to your harddisc via vobcopy than dvd decrypter

is that correct ?

well I haven't tried vobcopy, but I use dvdbackup (also a command line tool) and I haven't noticed any significant difference in speed (about 20 mins to rip an avg dual layer encrypted dvd)

Ok I will rip 3 different DVDs on some machines i can get a hold here locally.

I try to include all relevant information i find.
But dont know when i can do this, i am curious now tho.

mplayer dvd://1 -dumpstream -dumpfile video.vob is the fastest for me.

I really don't understand why people always suggest using mplayer with -dumpstream (only one dash in each option!) for copying DVDs. Yes, it does work, but it loses the complete DVD structure (like information about track languages, subtitle colors etc etc).

Isn't this information in the ifo file? Anyway this just works for me, with vobcopy I had some problems. Using the same program for all can't hurt I thought.

Yes, that information is in the IFO file. Try "mencoder -alang de yourfile.vob", it won't work. Basically being able to use "mencoder dvd://1 -dvd-device /path/to/mirrored/dvd" is the Way To Go, so using -dumpstream here is counterproductive.

BTW: I've never had a problem with a simple...

mkdir /space/my_dvd
cd /space/my_dvd
mount /dvdrom
vobcopy -m

Which doesn't mean the are no bugs. But as long as that works I wouldn't use anything else.

dvdbackup seems to work just like vobcopy, there is no performance difference either : P
