Device reset to factory default


i have about 22 folders in my PC share folder but the wd tv live only sees 16.with the 16 it sees the WIFI streaming works of the folders it does read is a tv show folder in which i put three files. it sees the folder but says there is no media in the folder.the other folders it just does not see.

to resolve this it has been suggested that i do a device reset to factory defaults.

if i do this does it mean that i will have to install the latest firmware again? and would this be the best solution to resolve the problem. i would most appreciate any ideas or assistance many thanks

Factory Reset does not change the firmware.

thank you
