Video playback locks up Fuze, renders it unsuable

first i convert the media files entirely to avi since Fuze seems to have issues with any other type of file(as i’ve learned through experience).

then i use the required sansa media converter to make them playable on the Fuze. i also take care to do them one at a time since experience(and other user comments concerning this issue) indicate batch conversions often result in corrupt or unplayable video files.

ass an addon question to this, is there any reason why my Fuze no longer appears as a proper Fuse product in my Computer disk listings but rather as a generic usb device, once i installed the Fuze updater? just noticed that a while ago.
