i am not trying to start an argument, but give it time, all of your box's as you said are within the first year, which means you must have them connected to a phone line, the sky plus box exspecialy, as it states on the sky + package it must be connected to a phone line, I also said the computerised system started this month, so you should be ok for another 2 - 3 months, then after that, i dare say they will switch your viewing off. this system is 100% now in use and as you are probably aware the digi boxe's had a software update over the last week, some box's are still display version 2.8b or 2.8b*, but they will update soon to version 3.0.11 and version 1.23.k for sky+ box's which contains the new ammendment for switching viewing off after not being connected to the phone line if the customer is still within there 12 month contract, the software detects this from the viewing card which is updated at 5 minute intervils,
hope this helps further, i don't want start rumours but i have seen the memo which has been issued from sky technical and subscriber department, I will scan a copy on to a word doc and upload it for you to see, please bare with me.
