Ok Gang,
I've now connected the xBox 360 directly to the STB, and it works fine!! I did have to clone the MAC code from the router (this is not the 'routers' MAC, but the MAC of the laptop which I used to 'register' the Broadband connection with NTL).
I tried direct connection to STB with the 360's own MAC, but it didn't work (i.e. it failed to assign an IP).
As soon as I added the alternative MAC to the 360 as above - it worked perfectly.
The bad news is, it now means there definately is a problem with the router part of the equation...
The BT Voyager 1500 *is* xBox live compatible according to BT... so it must be something to do with the settings?!!
As "MTU" is a test of Packet data transmission, I thought it may be something to do with the fact I had the STB->Router wire extended through a CAT5 Coupler (i.e. I thought I was getting packet loss through overly extended crossover cabling... even though coupled we're still only talking about 25ft in length). This made no difference, and the 360 still failed the MTU test despite being only a foot away from the router.
Gooner - good shout re: DMZ, I'll give that a try... and I noticed that there is an option in the Router config to block intrusions... so I may try disabling that to see if that helps....
Thanks for your help so far!!!

Ok...
- Disabled the Intrusion detection
- Removed the Alternate MAC from the 360
- Added the 360's unique MAC to the DMZ
Still doesn't work.
- Rapidly running out of ideas!!!
Not wishing to sound like I have a defeatist attitude (after a near week of trying to get the frickin 360 to connect wirelessly to Live... but perhaps you guys can start recommending the
best Wireless Routers to use connected to NTL STB's, which are great for use with xBox Live??!
I'm about to see exactly how far a BT Voyager 1500 will fly when drop kicked through a brick wall...
