Thanks for your replies!
Yesterday, I've connected my TV to the USB Target port. Then, the X10 switches to USB mode, and the TV is able to access all the media files (including movies) of the HDD. This means I have a workaround for my problem.
Network connection would have been preferred (permanent network cable instead of USB cable to plug/unplug), but it seems that my TV and the X10 don't speak the same language!
The TV is able to access to all media files of a network computer. I suppose UPnP is used (not Samba), because only the media files are seen and accessed. Not like in an explorer.
With the X10, the TV only sees the audio files that the X10 accepts to share (DB only, not the whole HDD).
Not sure the limitation comes from the TV...
Of course, I know that the X10 is an audio player, not a video device. But it would be a nice SW improvement to have it UPnP/DLNA compliant, sharing all media files...
Ok, you will say : that can already be done with Samba...
