[Debburn-changes] Question about wodim

[JD]

Dear all,
Wodim man page says:
.

        To copy an audio CD from a pipe (without intermediate files), 
first run

            icedax dev=1,0 -vall cddb=0 -info-only

        and then run

            icedax dev=1,0 -no-infofile -B -Oraw - | wodim dev=2,0 -v 
-dao -audio -useinfo -text *.inf

Well since I only have one CD burner, I decided to break the
second step which pipes the audio into wodim, into 2 steps; namely:

icedax dev=/dev/sr0 -no-infofile -B -Oraw - > xx
cat xx | wodim dev=/dev/sr0 -v -dao -audio -useinfo -text *.inf

Here, I eject the source cd after the second invocation of icedax,
and insert the blank media, and then invoke the third step which
runs wodim.

But wodim fails as follows:

$ cat xx | wodim dev=/dev/sr0 -v -dao -audio -useinfo -text *.inf

wodim: MCN '886978115126' has illegal length.

So, my question is what is the difference between the pipe (assuming I 
had 2 cd burners):
icedax dev=/dev/sr0 -no-infofile -B -Oraw - | wodim dev=/dev/sr1 -v -dao 
-audio -useinfo -text *.inf
versus this pipe:
cat xx | wodim dev=/dev/sr0 -v -dao -audio -useinfo -text *.inf

where xx was saved from
icedax dev=/dev/sr0 -no-infofile -B -Oraw - > xx

Why would wodim complain in this way since in both cases it is getting
it's input from a pipe?

PS: The reason why I wanted to do this is because I though this would
include CD Text in the CD I wanted to burn.
If this is the wrong way to go about doing that, please enlighten me,
and probably many others on how to achieve that.

Cheers,

JD
