On my laptop, mplayer has a problem with the AC3 audio (not
compiled in), so I can see the video, but not listen to the audio.
I think the installed version came from livna. (that's the version
that came shipped with the laptop.) Totem seems to have no
problems playing both audio and video though.

uhm, unlikely


On my desktop/server machine, it plays the audio and the video just
fine. (for some reason, I'm running the ATRPMs version on my home
server. Maybe because its also the MythTV server.)

Can't install the ATRPMs version on the FC6 laptop. That'll have
to wait until I upgrade the FC6.i386 to F8.x86_64. Probably some
time after the new year.

Whether the files are strict MPEG-2, I can't tell you. The file
command

seems to think they are some flavor of MPEG-2:
MPEG sequence, v2, program multiplex

something quick and easy (only remuxing, no re-encoding required):
run $ mkfifo /tmp/fifo , then:

$ mencoder -of mpeg -mpegopts \
format=dvd:tsaf:interleaving2 -o /tmp/fifo -oac copy -ovc copy \
file1.mpg file2.mpg

and on the other:

$ dvdauthor -o dvd_dir -t /tmp/fifo && dvdauthor -o dvd_dir -T

If all is fine in few minutes you will have a burnable dvd_dir
directory:

$ growisofs -dvd-compat -Z dvd_dir -dvd-video -udf -R -J

Notice that if the bitrates (of the video or of the audio stream)
are too high the first pass will likely lead to errors and you will
have to reencode at least the video stream (read the docs
in www.mplayerhq.hu for details)
