Data DVD Burn Failed

[Skavenger]

Hello,

I have recently bought a BTC DVD +/- Recorder, model DRW1004IM, I burnt my
first DVD RW no problem about 4.0GB consisting of 4 VHS Film Transfers.

The next DVD is where I encountered problems, I tried to back up about 4.3GB
of data from my Hard Drive organised into folders, I used a "Sky" DVD+R and
Nero 5.5.10.33, which came with the Drive. After a few complaints about
naming conventios and depth of folders, which I ammended, the DVD burnt away
very slowly though, about 15 / 20 mins.
Nero reached about 99 percent and started the lead out stage and BINGO The
message "Could not perform end of Disc-at-Once".

I have scoured the Net and found lots of examples of this that state that it
is a Nero compatability problem, one post said that versions of Nero 5.5 and
6.0 have the same problem and to use 5.5.10.42, which I could not find on
the Nero site so I downloaded 5.5.10.54 the latest version of Nero 5.5.
I have since found Nero 5.5.10.42 but have read another post saying that
this has a similiar problem.

I have also read that this problem appears with some Plextor Drives using
Nero and I have read somewhere that the drive in the BTC may actually be the
same as a Plextor, is this true?

Anyway before I waste money and start a coaster production line I need to
know:-
Which version of Nero should I use?
Should I upgrade the firmware on my DVD Burner? I have downloaded V043 from
the BTC site but they state not to upgrade if the drive is working which in
theory it probably is!!

Thanks in advance
