WD TV Live no longer recognizes any video files

There seems to be a weird issue with the 2.01.86 firmware I haven’t yet been able to reproduce. It happened to me on several occasions that files would not play when I had switched on the WDTV (completely powered off before). What fixes this everytime is to turn on the WDTV and change the TV channel to it and watch the whole boring process. Only when it’s completely booted up, I attach the HDD and now all files play again. Wether it’s a handshake thing between WDTV and TV or WDTV and HDD, I can’t say but this routine always works for me.
