Been away suitcasing for a few days, but S3 card has been back back in for a week and all normal at the mo inc. WM Player. Will advise!
EDITED TO ADD Adaptec 'Direct CD' (enables use of CDROM as read/write drive) DID work but does not now - 'drive will not support etc'. Can still 'create' normal CDRoms with Data or audio content
Does a Video card change affect CDROM operation?
Further edit On 3rd re-install of CD prog now all well
