I'm new: MPEG2 from VOB file

[corbetz]

Sorry, I'm new and the search engine is out of order.
I recorded several episodes of my favourite drama with my DVDR standalone (on DVD+RW). Now I'd like to re-organize the episodes using my PC and burn them again on a DVD-R with my Sony DRU.

What I need to do is:
- extract original high-quality Mpg2 file from a VOB file I ripped on my HD thanks to DVD Decrypter.

- once I have Mpeg2 file (video and audio in only one file or video and audio in tho separate files) I will organize them with Ulead DVD workshop (menus, graphics ecc.) and burn on a DVD-R.

Is this possible ?
Which software (freeware if possible) do I need to do this ?

Thank you !

Forgot to say that my DVD Workshop version does not accept AC3 audio files....
