finalizing DVD+R media ?

My apologies if this is a recurrent question but some amount of
searching of the mailing list did not bring any working solution.

I have an unfinalised DVD+R media (recorded on a Philips HDD/DVD recorder)
which I am unable to read on any of the Windows/OSX/FreeBSD machines
I have tried. The recorder itself is however able to read data from
the disk (a 2hr recording from TV).

So far nothing strange -- however, I was wondering if there is a
way to 'finalise' or otherwise write something to the media so the
data is actually accessible to other devices than the DVD recorder
used for its creation.

I have unsuccessfully tried the following:

    + cdrecord -fix
    + growisofs -dvd-compat -M /dev/cd0=/dev/zero
    + the "close.cpp" program from Andy Polyakov

none of them managed to render the disk readable, usually failing
with some "illegal command" error trying to write to the device,
and complaining because of "incomplete track" or something similar.

To know what's on the disk i ran "dvd+rw-mediainfo" and "cdrecord -minfo",
the output is attached below.

What looks confusing to me (and to the two programs as well, i guess)
thing is that the "Next" track is reported as #1 even though
the number of tracks is listed as 2. Some of the error reports from
the above programs mention address mismatches related to this.

I wonder, is there any set of growisofs/cdrecord/somethingelse
options to make this disk readable ?
