Thanks again Fengtao- fantastic work.
One problem with merge - tried to do a DVD compilation using 8 music DVD's on HDD.
Selected 2 chapters from each disc but FAB would only let me select HDD source maximum of 6 times. Then I kept getting the FAB advice notice asking me to send error report.
Tried this 3 times - every time I selected the 7'th disc on HDD got the notice.
Did the compilation with only the 6 sources selected = perfect copy and in only 9 minutes. What an excellent feature.
