Virtual file error in VOB2MPG Pro

[lmocsi]

Hi,

I'm using VOB2MPG PRO 3.2.2000, and regularly it produces the correct mpg out of VOBs.
But for some DVDs (e.g. Clear History), it says:

20:37:55 Extracting chapter: 8... Done.

20:37:55 Finished Processing...

And the output file will be 4 minutes shorter, than it should be.

If I say in a command line:
> copy /b *.vob file.mpg
Windows produces the correct mpg (but with all the audio tracks).

What is the problem with VOB2MPG PRO?
Please advise (or fix it).

Thanks,
Laszlo

How do you rip? Maybe some strange dvd protection.

With DVD decrypter 3.5.4.0
But it's all after any DVD protection, since I can copy them together...
