A physical DVD could be played but not copied, despite attempts on multiple computers (each with own drive). The main VOB file was corrupted. The disk appeared to the eye to be in good condition. Wanted to copy a repaired version of that file, maybe with gaps or truncations, whatever could be salvaged. Workaround was to do a ‘dd’. That’s a unix command to “convert and copy a file”. Mac OS X is based on a variant of unix, so chose to execute it from there. The successful command was as follows:
- dd if=/Volumes/’DVD VR’/VIDEO_TS/VTS_01_1.VOB of=tmp/vts_01_1.vob conv=noerror
Prior to this, naively-and-unsuccessfully tried Windows 7 PowerShell (PS) ‘cp’ command with ‘-Force’ option, but that was “barking up the wrong tree”. An alternative suggestion, not attempted, was to use a streaming video processor such as VirtualDub.
