Can I stream on by IPad and then stream the content to a TV while traveling?

I hope I am not asking a really stupid question.  I tried searching, so feel free to just point me to the right place.

I am able to watch my recordings using the streaming AP on my IPad.  Each year I rent a Condo for four weeks.  I am interested in “streaming” or mirroring what I can watch on my IPad to a TV.  Last year I tried using my wireless Memorex device from my IPad to the TV.  I was successful for many things, but I got a message that my device does not support Xfinity. (Or the message may have been from from Xfinity).

is it possible to stream via my IPad to a TV?   I want to watch my Xfinity recordings on a TV when not at home. If it is possible, what devices support Xfinity?

Thank You
