hi everyone!

for the first time ever, i have to prepare a cd-r master that will go 
into production without verification by the plant (yeah, i know, but my 
client got a *really* cheap deal ;)

so i will have to make sure the data is ok and the block error rate is low.

* how do i measure BLER on CD-Rs with free software tools?

* how on earth can the same content burned via cdrdao to a CD-R on a 
cdrw drive (Plextor) and a dvdrw drive (LG) differ in several hundred 
thousand bytes when read back in with cdparanoia?

both drives seem ok, i frequently use them to burn data cds and dvds 
which perform ok.

any hints welcome, tia,
