V.Impressed your qouting from the manual, unfortunately I have tried all of those and below is the findings...
V.CONV OFF - 1 second display then no signal (no options to change res, pcinema, smoothing etc when off) (this is what I have set for the PS3)
PCINEMA ON/OFF - didn't seem to make any difference.
RES (With the execption of 1080/24P) - 1 second display then no signal.
V.CONV ON RES (1080/24P) - Works, but any XBOX display setting (i.e 720P) upscalled.
* Tomorrow I will try all the HDMI cables I have as I need to tidy up the mess I've made so far installing the amp
** It would be good to know if anyone else has this working on this particular AV Receiver
