A lot of hotel TV's these days have USB ports and I've had no problem plugging in a key that has .avi films. Works great. Why wouldn't it also work with HDMI and this new dongle?

But I have a question, will this dongle work if I carry it to Europe? HDMI is a global standard, but what else is happening under the covers? Any issues between NTSC and PAL? Is there a complete technical description of this gadget somewhere?
