Vista keeps saying this is a CD; it will not recognise it as a DVD. I have read that I should go to the registry and delete the referances to upper and lower limits, but there are no such references in my registry. It is an ATA thing.

That registry fix is only for drives that are not detected, ie: not visible in My Computer.

Do you have compatible 3rd party recording and dvd decoding software installed? ie: Easy Cd Creator or Nero and WinDVD or PowerDVD? If not you will need to obtain install.

Windows Vista has built in support for burning cd-r disks but not for burning dvd disks.

Thanks Jerry. I appreciate your help and hope you win the lottery. Are any freeware programs available that will do the job?

Phil

sure, just do a search for free recording and free dvd codecs.
