Vaio PCG-3B1M HDMI OUTPUT PROBS,

[EODC Rs-Bandit]

as im a newbie had no idea where to put this, so soz to admin in in wrong place.

I am asking on behalf of a freind,

I was wondering if anybody could help me out.I have just bought a blu-ray disc to try out.I put it in my computer and it works and plays the disc.Now this is where I have the problems.I have a hdmi output on laptop to connect to tv.If I connect it I can see my desktop on the tv which works fine.But if I go to play the blu-ray to watch on the tv it starts then stops and says that the external device doesn't support disc format.
This is the bit I dont understand.I have set up as said im manual,my tv is hd compatable so dont know whats going on.
I am thinking that the computer is thinking I am trying to connect to a device to record it.
Anybody shed any light on this?

I have just watched 30 days of night on it.The laptop is only a week old and its a good spec vaio 1.It is saying the external device cant support it?

Any help is gratefully apprecited by both of us.

thank you.
