Last chance to quit, starting real write 0 seconds. Operation starts.
Waiting for reader process to fill input buffer ... input buffer ready.
BURN-Free is OFF.
Starting new track at sector: 0
Track 01: 4273 of 4273 MB written (fifo 100%) [buf 94%] 3.8x.

Writing time: 847.981s
Average write speed 3.8x.
Min drive buffer fill was 91%
Fixating...
As you can see the average speed was 3.8x, which is slower than the
earlier versions of cdrecord. Remember these are 16x disks.
I downloaded and ran the 01a26-pre2 version but the heading still reads a25.
