Hello ML!

Thanks to xeatre for releasing it to the pubic and to Sascha Volenandt 
for writing it!

One thing I saw when first using the plugin was that it didn't find 
requant nor vdrsync.pl in /usr/local/bin. I had to move those two to 
/usr/bin.

Can the plugin be changed in a way that it's possible to select the 
audio streams for the DVD? That way you can trade space for quality and 
time in case no requant is needed after dropping audio. For instance, 
you choose the AC3 stream and leave out the MPEG audio stream(s). 
Afterwards the factor for requant should be (re)calculated. Maybe after 
dropping some audio streams no requant is neccessary at all.
Another nice thing to have would be chapters. Like having a new chapter 
every 5 minutes or so. I changed xml.c like so:

const char *DVDAuthorTitleFooter =
  "    </menus>\n"
        "    <titles>\n"
        "      <pgc>\n"
        "        <vob file=\"%s/movie.mpg\" 
chapters=\"0,5:00,10:00,15:00,20:00,25:00,30:00,35:00,40:00,45:00,50:00,55:00,1:00:00,1:05:00,1:10:00,1:15:00,1:20:00,1:25:00,1:30:00,1:35:00,1:40:00,1:45:00,1:50:00,1:55:00,2:00:00,2:05:00,2:10:00,2:15:00,2:20:00,2:25:00,2:30:00,2:35:00,2:40:00,2:45:00\" 
/>\n"
        "        <post>call vmgm menu;</post>\n"
        "      </pgc>\n"
        "    </titles>\n"
        "  </titleset>\n";

Then I got chapters every 5 minutes. It seems dvdauthor doesn't care if 
the movie is not as lang as the chapters it is given in the .xml file, 
which is good for generic use.

I also changed process-dvd.c like so:

SetCmdline("vdrsync.pl -ignore c0,c1 -o %s/VDRSYNC.%d \"%s\"", 
TempDir(), rec->Number()

That made vdrsync.pl ignore all streams other than the ac3 one. The 
result was ok, but requant still used the same factor like it did with 
the c0 stream and the ac3 stream. growisofs reported

2023069 extents written (3951 MB)

That gives me the idea that the requant factor could have been smaller. 
Seems like the factor is calculated from the VDR recording size and not 
from the streams vdrsync puts out?

Thanks regardless if you add this features ;)
