ok here is my frustrating issue with the boxee box (hardware device not software app)

I find a film on my pc to play, it starts to load but the film is in a format boxee cannot play...so the screen goes blue with a "mode not supported" message. Now what ever i do with the remote buttons i cannot get boxee user interface back, it beeps when i hold center button but nothing, nothing ever,

while playing a film boxee recognises i click the button sequence to come out of palying the film back to menu choice (to learn the sequence), i tried this while in "mode not supported" scenario but nothing, I cannot get back to boxee UI....is there a way to get back from "mode not supported" other than a hard reset?
