Is 1080p "too much" for Live TV on the Pi?

I'm afraid that I would not be able to help much here as I mentioned before I do not have any tuner so I do not use PVR functions at all, so I do not have such experience to tell or discuss.

I found some talk on XBMC Forum about this issue so maybe you would be able to get some more information over there.
As I said, this would be caused more likely by MP addon for XBMC or by player what is used in XBMC on RPi to play the stream is simply not good for this. But all these are just my deep guesses.
