I tried doing data rescue from a damaged DVD using ddrescue with a Pioneer BDR-TD05AS that is new to me, and was surprised that a rescue of supposedly 100% produced garbled video.
I associate this behavior with LG drives and their "Jamless" playback feature, which handles damaged areas of a disc by not indicating that errors occur, and instead outputs junk data. Do Pioneer drives have a mode that does this as well? I assumed that the "PureRead" mode in Pioneer drives is only for audio CDs.
