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

regarding to the Live playback I think this would not be HW problem but more likely SW and specifically PVR addon.
The RPi is capable to play Full HD 1080p (even 10bit files, but with limits atm) so I would not see this as an cause of this stutter.
As I said, more likely the limitation rely in PVR function
