I've just added a USB DVD drive to my Acer Revo R3160. I can play dvd's from the drive but I can't navigate menus from my keyboard. Left/right cursors seem ok, but i can't select menu items by pressing enter. up/down cursors seem to behave as left/right also. When playing ISO's from HDD, all menu navigation works ok. Playing external DVDs though Windows media centre works fine too.

Any ideas? Using Dharma 10.0 on windows 7 32-Ultimate
thanks
