I also tried the latest firmware and it made no difference
Check your software environment - drivers, especially IDE drivers, and any other software which may stress your IDE bus beyond capacity, including other burning/reauthoring software and virtual CD/DVD drives.
Chipset-specific IDE drivers are known to be a potential cause for serious conflicts, so if I were you, I'd revert to standard M$ IDE drivers and take it from there.
