First I get a file opening problem with avidemux2 with an original file. So I tried a transcoded file (MPEG with MP3) and this is working.I'd be surprised if there's not a way to save the raw streams anymore. I'm compiling 2.0.36 now (didn't notice it was updated), so I can't check yet. In general, I've discovered it's a bad idea to strip out the raw video and audio and then remux. Once they're an elementary stream like that, there's no sync information anymore. Most of the time it's fine, but sometimes a capture will sneeze out and change A/V sync in the middle... then you're hosed.
But the HowTo seems to be very old. There is not button "Save Raw Video Stream" in version 2.0.36 anymore. So I tried there the codecs DVD and FFm MP2.
I get an encoded *.mpg in this format. But when I try dvdauthor -o DVD this.mpg I get a segfault because no VOBU is found. I only get very very much warnings about skipping sectors because of waiting for the first VOBU :-(.
My guess is you've got a Program Stream (PS) with audio and video, but it doesn't have the necessary stream to put on a DVD. The best tool I've found for looking at that is from the 'transcode' package. Run 'tcscan -i file.mpg'. You want to see something like this:
tcscan -i sync_k_replexDVD.mpgfound first packet header at stream offset 0x0
found unknown stream [0xbb]
found navigation pack [0xbf]

This shows that in addition to the video (0xe0), audio (0xc0), and some padding (0xbe), there are some other streams necessary for DVD's... 0xbf for NAV packets.
If that command spews lots of packeted presentation units like this:
------------- presentation unit [89] ---------------

it's probably not quite as DVD-friendly.
So I need somebody here who can tell me what I'm doing wrong and perhaps can bring the documentation up to date...
Bugs are definately still being worked out of the process.
