zapping without restarting the stream

Please tell me if I'm chasing my tail (going around in circles).

I've been trying to stream from my XP1000 the same way as I can on my DM500 (boxip:31344), where I can change channel on the box via remote without stoping the stream.

Is this possible?

This is the closest thread I could find (2008)
