Re: [Libcdio-help] 44 bit difference

[Robert William Fuller]

So it was a 44 byte difference, not a "44 bit" difference.  I might have
guessed something like that if you had said "bytes" instead of "bits" in
the subject.  It helps to be very careful when you state a problem.  I'm
glad to hear you solved it :-)
