Just curious ... aren't there funnies because CD's are normally 1024 byte blocks and disks are usually 512? IIRC, there are places that store numbers of blocks (not bytes), and you have to be careful. I have >>not<< played in any of that in years. IIRC one of things we might have done at DEC was mess with the block size on a CD -- that's a Tim Litt type question. Those bits are so long ago depreciated/garbage collected in my acitve brain cells. ;-) ᐧ
