vstrip command line

[hellgauss]

When i use vstrip i have an "expecting PACKET_START_CODE_PREFIX!" error.

this is the command line i use and its output:

D:\tmp>vStrip @D:\tmp\stream.lst -iF:\video_ts\vts_01_0.ifo -p0 -$1024 -ofileout
.vob

Did you authenticate your DVD drive?

Ops... I'm sorry, SmartRipper didn't need drive authentication, and so i thought that vstrip didn't need too.
I've found a good Open source authentication program on a link in this forum. Thanks

However i've still got a lot of problem.
I've ever used SR to rip dvd, with this command line:
smartripper -Cs "F:Video*" "F:Audio*" -So lucxi -Cr -Cq -Cf -Co "[path]"
It works quite well: it produces some vob with the main video,and some ac3 files.
When i play the ac3 file in WMP it doesn't play well (the sound is discontinuous) but i think that there are some problems with the decoder (i've installed the audiofilters suggested by doom9), because when i encode it in wav with azid (azid -c normal -L -3db "file.wav") the wav output is perfect and there are no errors.

The problem is that i want to do an automatic utilities for dvd to divx rip and i don't know if i can include SRipper in my software (while vstrip is general public licence) and so i want to do the same thing i do with SR with other programs: i need only a chain of vob with the video stream to open with dvd2avi and an ac3 file (from 0x8n substream) for azid. I've read doom9's guide about vstrip, but it doesnt work! I can extract ac3 audio, but the ac3 file plays VERY discontinuous on WMP and when i encode it with azid i get thousands of "crc errors" (what does it means?). And if i open the vob files with dvd2avi i get a green preview.

However i've learned how to use vstrip to find the main video vob file and to find the right audiosubstream for my language.

Now i've got 2 questions:
1)What's the correct vstrip command line setting to obtain the video and the ac3 files like smartripper do?
2)What kind of license SR has? If it has General Public L. there is no problems because i can continue to use it.

PS My configuration is P4mobile with WinXP installed.I've installed forceaspi

PPS sorry for my bad English, i'm Italian.
Tnx
