First example is my usual case: dvb(-t) recorder file in .ts (transport stream)
format is demuxed, "edited", cut and finally written to dvd:

1) Demux recording using ProjectX (ProjectX can be used to demux other types
                                   of mpeg[12] files too).

$ /path/to/java -jar /path/to/ProjectX.jar rec.ts

2) Run lve and find suitable cutpoints:

$ /usr/local/lve/bin/lve

3) Do testrun:

$ m2vmp2cut --test=200 +

$ mplayer ,,,/out.mpg  (now use numpad + and numpad - to check sync, and
                        rerun mplayer with -delay option to do final check).

4) Do "final" cut, have same value (same sign (+/-)) for --sync as above
   if needed.

$ m2vmp2cut [--sync=nms] +

5) dvdauthor material:

$ cat >! rec.xml <<EOF
<dvdauthor>
    <vmgm />
    <titleset>
        <titles>
            <video aspect="16:9" />
            <pgc>
                <vob file=",,,/out.mpg" />
            </pgc>
        </titles>
    </titleset>
</dvdauthor>
EOF

$ rm -rf dvdvideo && dvdauthor -o dvdvideo -x rec.xml

6) Burn it (replace /dev/hdc with your dvd burner device):

# growisofs -dvd-compat -Z /dev/hdc -dvd-video -udf dvdvideo

--

Next some old examples:

 m2vmp2cut +
	- Just do it after editing with lve.

 m2vmp2cut --sync=200 +
	- When testing original (undemuxed) file with mplayer, 
	  using --delay=0.2 gave good a/v sync.

--

Now something slightly off-topic -- test your dvd player xsvcd playing
capabilities:

$ wget http://www.starwreck.com/media/itp/star_wreck_itp_trailer_mpeg2.mpg
$ tcextract -i star_wreck_itp_trailer_mpeg2.mpg -x mp2 > swr.mp2
$ tcextract -i star_wreck_itp_trailer_mpeg2.mpg -x mpeg2 > swr.m2v
$ mplex -f 5 -o swr.mpg swr.m2v swr.mp2
$ vcdimager -t svcd --iso-volume-label="Star_Wreck_Trailer" swr.mpg

... Put blank cd-r/cd-rw to your cd/dvd burning device ...

$ cdrdao blank --device /dev/hdc --speed 4    # No need to blank cd-r.
$ su
# cdrdao write --device /dev/hdc --speed 4 videocd.cue
# exit

My player succeeded to play this without hiccups, but all other (consumer dvd)
players I've tried have had some cd reading speed problems (no smooth playing).
