I am still using DVD Studio Pro 1.5...yeah I know...Just bought Plextor external DVD drive...716UF...It will play DVDs fine, but I am having a problem recording with DVDSP. When formatting the drive is recognized along with my AO4 drive, I select the Plextor and insert disc, then get a error 37 formatting error. I have tried patchburn, but am not sure if I am using it correctly. Please help!!!

Keep in mind that burning program generally must support your drive. If this
is a new drive it may be a good bad that your (old) DVD SP version simply
does not properly use this drive. Perhaps it is time to upgrade to DVDSP 4?

I ended up having to do a double patch and treat it as if my drive was not recognized at all and now it works fine. You are right about the upgrade though. I just have custom templates already built in 1.5, so haven't found the urgent need to upgrade...call me old school.

Well, if it works (for you) then there is no need to upgrade indeed. Glad you
got it resolved!
