hi,
i just registered to share some interesting information with you.
You can activate your usb port to play music, photos and movies (mkv´s with 1080p working!) through the service menu. (LH 3000 - 7000, maybe 2000 too)
You can reach the service menu by pressing "OK" on your remote and "OK" on your TV. Password is "0000".
Once you entered the service menu, go to option 3 and change "divx movie playback via usb" to "HD". Change JPEG to "1".
Use the return key on your remote to leave the service menu.
Now you can use your USB port to play Videos, even 1080p mkv files
Greetings
