Brill thanks
At the moment I have belkin pure av hdmi cables, it said on the box v1.3b. So don't know what that means!
This goes from my ps3 into my Sony dh-800 amp and them from there to the tv. When the ps3 loads a blu ray disk sometimes the tv sows full hd res at 60hz before settling down to full hd at 25hz.
Do I assume my cables support high speed?
