Full iPad Mirroring with aTV Flash black

I just purchased aTV Flash Black and installed it after jailbreaking my new Apple TV 2.  After doing so, i discovered that full mirroring of my iPad 2 does not work.

Is it something I might have did? … or does this jailbrak + aTV Flash black not support mirroring (as per a non-jailbroke device)?

If it is the latter, can I unjailbreak my device?  Mirroring is more important to me than the added features that I acquired.

Thanks in advance.

Mirroring works fine for me, but AirPlay for me will not work via the YouTube or Trailers app. Other apps that use AirPlay work fine. Also, check out this thread for more discussion on this topic:
