Given what we're looking for, I think you can ignore normal packets:

	tcpdump 'host ps3 and tcp[tcpflags] & 0x27 != 0'

(substitute the hostname of your PS3; you may need to escape the !  
depending on your shell)

This (flags = SYN, FIN, RST; URG thrown in for the heck of it) should  
omit all data packets from the capture.
