Manual read speed selection for ltd122?

i have problems in reading some burned dvd-r with liteon ltd122 and ltd163 due to high media speed in the outer sectors. when reaching high read speed the drives report errors, allthought slower drives and of course the burner read the discs without problems.

is there a firmware available which allowes the selection of the read speed? the drives allways select the speeds by itselves and i want to prevent that. all the knows tools unfortunatelly dont work.

No there isn’t. NERO DriveSpeed doesn’t work?

no. detected speed is ‘maximum’ and manually added speed automatically result in 12x :frowning:

is there a possibility to patch the firmware?
