CloneDVD 188.8.131.52, WinXP Pro SP2 I'm simply trying to create an ISO/UDF image. I'm on the last screen, but the Go button is disabled, and I have no idea why. I have everything filled in. If I use the DVD files or DVD writer functions instead, the Go button is enabled as expected. CloneDVD is giving me no clue whatsoever as to why the Go button would be disabled. Advice, please.
