Quick question someone I hope can answer..
Have the following setup..
Samsung LCD 40"
Rogers Explorer 3250 HD Cable Box
Sony 40" HT-CT550W
All above are connected with HDMI 1.4 cables as usual.
However, when I change the channel on the Rogers cable it takes 10seconds to display or hear anything. Oddly, if I disconnect the HDMI cable from the LCD TV then I can change channels and hear them quickly but obviously no video shows

If I direct-connect the Rogers -> LCD then changing channels happens almost instantly.
Whats at fault here?
Why is changing channels so slow between Rogers -> Sony 40" HT-CT550W -> LCD ? How to fix this?
