Thx, this worked well with dvrescue device://0 --merge-output-speed --merge-output-concealed -m speed_concealed.dv --merge-ignore-speed --merge-ignore-concealed -m nospeed_noconcealed.dv --merge-output-speed --merge-ignore-concealed -m speed_noconcealed.dv --merge-ignore-speed --merge-output-concealed -m nospeed_concealed.dv

Though I noticed without the input reference, such as dvrescue --merge-output-speed --merge-output-concealed -m speed_concealed.dv --merge-ignore-speed --merge-ignore-concealed -m nospeed_noconcealed.dv --merge-output-speed --merge-ignore-concealed -m speed_noconcealed.dv --merge-ignore-speed --merge-output-concealed -m nospeed_concealed.dv then the command seems invalid (though I thought with no input then device://0 would be default).

I also realize that perhaps the xml and scc outputs also need to be output specific. In the example above the 4 outputs should have different xmls.
