|Well, the HDD's are from different manufacturers: LaCie & Western Digital where both are as well portable as desktop models.|
TV's are Philips, Samsung and LG. They support USB connection, with auto run (at least) for JPEG and MP3 and for multi Media drives.
However, external HDD are not in autorun mode for movies (DIVX or other), but I guess that one could fix that with an autorun.inf file.
Thanks in advance for your help!
