Hi Joerg...
I read over my e-mail and felt I had left something out, sorry.
Both the working and non-working CDs were made using cdrecord.
The working CD was made using the inf2cdtext.pl PERL script to
make a cdtext.dat file. Then, I used cdrecord and this file to
create a working CD.
Something like:
cdrecord -dev=0,0,0 -v -dao textfile=cdtext.dat *.wav
The non-working CD was made using just cdrecord.
Something like:
cdrecord -dev=0,0,0 -v -dao -text *.wav
Do you think this is consistent with a buggy CDROM drive?
...thanks, [EMAIL PROTECTED]
