No - everything looked fine.

Yes.  I have also re-built the .raw, but with the same results.

Dvdauthor is 0.6.8.
The disk plays fine on a Daewoo, but stutters terribly on a Toshiba.

Commands used in preparing the disk were:

dvdauthor -x ../my-dvd.xml
dvd+rw-format /dev/hdd -force
mkisofs -dvd-video -o cottingley.raw /Data/Movies
growisofs -dvd-compat -Z /dev/hdd=3Dcottingley.raw

The contents of my-dvd.xml -
<dvdauthor dest=3D"/Data/Movies/">
	<vmgm />
	<titleset> <titles>
		<pgc>
			<vob file=3D"intro.mpg"/>
			<vob file=3D"cottingley.mpg"/>
			<vob file=3D"codaDVD.mpg"/>
		</pgc>
	</titles> </titleset>
</dvdauthor>

Tried so far:
Original test was to burn the 2-minute codaDVD.mpg onto a dvd+R disk, and i=
t=20
played correctly on the Toshiba.

=46ull authoring as above - the silent intro appears steady (it's only 5=20
seconds), and the machine-gun stuttering starts about 6 seconds into the ma=
in=20
stream.  If you fast-forward then play on you get around 6 seconds again=20
before the stuttering cuts in.  The coda stream is not as bad, but it does=
=20
stutter, which did not occur in the original trial burn.

Onto a dvd+RW I burned just the main stream.  The stutter is the same.

I tried burning through k3b.  Again there were no error messages.  Again th=
e=20
stutter remains. =20

=46inally, I have tried telling k3b to force a 1x burn.  The result is the =
same.

My Toshiba will not read -R or -RW disks.  I'm completely out of ideas.
