Which version are you currently using? If you’re not using 188.8.131.52, please update. As my good friend signals suggests, TV series discs are “screwy”…definitely try disabling PP. If already disabled, try enabling.
Do not choose “Enable PathPlayer when necessary”.
To be honest, I can’t remember the last time I couldn’t bkup a disc with Fab. When a problem does arise, frequently, with some tweaking, you can make it work.
No software works perfectly on every disc, everytime.
