Pioneer DVR5100 - connections and controls

I'm tempted to get the DVR5100 from digital point for £500.

I have the 757 dvd player, and ax5i amp and a p5 panny plasma, tuner box and NTL digital cable box.

Does anyone know if I can use the I link connection to the amp?

What would be the best way to connect it all together?

Will the two dvd pioneer controls confuse each other? - can i record with one while i watch a dvd?

Has anyone had experience recording withe ntl cable? I can rarely get the tv info to display for the day - let alone a whole week a head!

Any comments would be greatly appreciated.

Thanks

John
