Blankhi folks i installed a program called sound taxi, thanks Albert, to play m4b files, but i get an error when i go to convert the book file concerned saying i need to install QuickTime 7. i have been searching the net in vain looking for a free version of this program but no luck. most sites start off with a free announcement and end up at step 3 with something like ' yours for only $99 per hour'. anybody got any ideas? or is there another program i could use that won't need QuickTime? regards and thanks Paul H
