\fBmax_lba=limit\fR
switches to what=disc and omits all blocks above limit.

sets the number of bytes to be read in one low\-level read operation.
This gets rounded down to full blocks of 2048 bytes. 0 means automatic size.

forces read retries with single blocks when the normal read
chunk produces a read error. By default, retries are only enabled with CD
media. "retry=off" forbits retries for all media types.
forces read retries with minimal senseful chunk size when the normal read
chunk produces a read error. This size is 1s with CD and stdio files,
16s with DVD (1 ECC Block), and 32s with BD (1 Cluster).

Choose one of "good", "md5_match", "slow", "partial", "valid", "untested",
"invalid", "tao_end", "off_track", "md5_mismatch", "unreadable".
.br
"valid" and "invalid" are qualities imported from a sector_map file.
"tao_end" and "off_track" are intentionally not readable, but not bad either.
"partial" are blocks retrieved from a partially readable chunk. They are
supposed to be ok but stem from a suspicious neighborhood.
.br
"md5_match" and "md5_mismatch" regions overlap with regions of other quality.
.br
\fBslow_limit=threshold\fR
sets the time threshold for a single read chunk to be considered
slow. This may be a fractional number like 0.1 or 1.5.
.br
\fBchunk_size=size\fR
sets the number of bytes to be read in one read operation.
This gets rounded down to full blocks of 2048 bytes. 0 means automatic size.
.br
\fBasync_chunks=number\fR
enables asynchronous MD5 processing if number is 2 or larger.
In this case the given number of read chunks is allocated as fifo buffer.
