Everything is supported if your receiver supports it....
PLIIz is just a processing technology that expands audio tracks to provide "height", it's not a native audio format on any BD as far as I know.
Bear in mind that to get both 7.1 native sound + DPLIIz, you'll probably need a 9.1-capable receiver (typically your B Speakers are connected as height fronts).
Edit: Not sure if your S5300 receiver does this, it'll probably be surround back OR height front configuration, not both at the same time. FWIW.
The intro/start to Saving Private Ryan
I heard Master and Commander (the one with Russell Crowe on the high seas) is a good one (but I have not seen it personally)
The shoot out scene in the movie HEAT.
Val Kilmer and that automatic rifle comes out spatially fantastic on a good system.
