That is supposed to be -tao write mode.
The other write mode may be triggered by
option -sao.

This might well be the known "read-ahead"
bug of Linux.
(It's name stems from a misunderstanding
about a too-stupid-for-TAO bug.)

In this case option -sao will help too.
Alternatively this option may be used with
TAO write mode:  padsize=150s 
"150s" is superstition which works. Actually
it has to be larger than the read buffer
of the Linux CDROM block device.

The "read-ahead" bug matches quite well with
your description:
- Vista has different bugs
- cdrecord and Nero might have added more
  padding or might have used -sao by default

cdrskin would use SAO by default with
  cdrskin ubuntu-8.10.iso
because the file size can be determined
before burning begins.
(Mode TAO allows to start burning with
 unknown data size and to end the burn
 when the input stream ends.
 Mode SAO needs the size in advance and
 wants exactly the predicted number of
 data bytes.)


So my proposals with wodim are -sao or
padsize=150s .


Have a nice day :)
