To me, Sankisk seems to be a major infringer with all the flash based portable video players they have including this one I personally own.

I load AVI (DIVX) files to the USB flash drive and then connect the flash drive to a docking stationg. Then with the remote control I paly the files on my TV.
You can only use the flash drive that comes with the player. Seems the player is embeded in the flash drive.
Cheers to all longs.
