Done a fair bit of reading but really hasn't helped

Current digital/HD set up Sky HD, PS3 and Sony Vaio Blu ray laptop. Might also invest in dedicated Blu ray player!?!
I definitely want the receiver to upscale HD contents to TRUE 1080p 24fps (PS3 an other blu ray player's) without losing quality of the picture. HD sound as well with 7.1 ch.
The LX70 has come up quite frequently by reading many posts.
What concerns me now is this thread:
VSX-LX70 DCDi version and 24fps..?
I thought most if not the Pioner VSX LX/50-70 series are capable of TRUE 24fps?
