I have a standalone DVD Recorder which records in DVD+VR format. These discs play fine on my Mac, and I can easily extract the video, either with MacTheRipper or with Toast.

However, the only way to burn these videos back (after editing out commercials etc) is to write them in standard DVD format. This means I cannot add any more video to the DVD+RW.

I know that on a PC there are programs which can write in DVD+VR mode, are there similar apps on the Mac?
