Thanks, it sounds simple, but good, you reminded me of first keeping an Image and trying that, I would have forgotten that! (no irony!)
As far as I see it now:
I need a) something to create the DVD-compliant files out of any source and b) something that will burn it onto a DVD with "structure" etc. so that it has a menue and everything.
Avidemux just creates the mpeg2 files one needs, while Toast and iDVD do encode and author (make a contents table etc.) the DVD.
I figured out the following (maybe there others that are stupid as me, so I can shorten their learing curve).
iDVD:
- through any file (xvid.avi, DV-avi, h.264,mov, mpeg4.mp4,...) in the first window of the menue.
- click burn. Nothing to select! (instead I didn't burn, I saved an image)
- the Application is encoding
- result, it doesn't give you options, it just say, this is what I choose for you and it is PAL-DVD compliant.
Toast
- you choose what kind of media you want to burn (Data, disc, audio-CD, SVCD, VDVD, DVD, copy, Image,...)
- you choose DVD and hit "options"
- you are only presented what is compliant with PAL-DVD. You can choose the bitrates, and if you like PCM or AC3, etc.
Avidemux
- auto-DVD is quiet straight forward
- it is no problem, that it doesn't grey out the other non-compliant codecs (when you google the specs. I used this table https://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-vcd-dvd.html - however it doesn't say that the 1.5Mbit/s belong to PCM and AC3 and MP2 is different)
- you can alter stuff, but some things are not intuitive (for me): e.g. that 2-pass is included in "variable bitrate" and "variable quantisation". But, if I think about it, it is quiet obvious, why you don't have to do a first pass, when you choose constant bitrate, for example )
- the guide http://www.avidemux.org/admWiki/doku.php?id=tutorial:converting_to_dvd added to the confusion (since some options are missing in 2.6.6, but probably the authors wanted to make it easier and more straight forward)
------> I know have to look, if actually creating the DVD will work with the mpeg2 file (which includes V+A) that Avidemux created. I don't want iDVD or Toast to encode DVD-compliant mpeg2 a second time, right?
iMovie
- I didn't bother, I had to much headache to come to this point, allthough I am happy, I only needed one evening for it 😉
