I have a home movie recorded on a Minus-R disc. It won't play on my desktop computer's DVD drive. That drive will play Plus+R's just fine, so I want to turn this minus-R into a plus+R so that I can play this home movie at my leisure.

My wife, purely by coincidence, just got a Vaio laptop with a DVD burner. It comes with Sonic RecordNow (formerly Roxio formerly Adaptec EZ CD Creator, if I understand the genealogy correctly).

I insert the Minus-R disc into the laptop and it plays fine. I run the RecordNow software and ask it to make an exact copy. It dutifully reads the contents of the source disc and buffers it on the hard drive. Then I insert a blank Plus+R disc into the drive and it tells me the destination disc is different type from the source disc so it can't make an exact copy. Sigh.

Can anyone help?
