I have a DVD recorder that records onto DVD-R discs. Problem is once the disc finishes recording the file is stored as a DVD-V format which renders it useless for playing back in portable DVD-R players! The guys at DSE told me to finalize the disc but that makes no difference, but I understand that I can get software to convert the format from DVD-V to DVD-R on my iMac. What is the software to get and is it freeware?

I'd appreciate your help

Cheers
