I really doubt this, or I am the only german customer ?
Perhaps not the only one, but a customer with cable internet - where you keep your IP address for about 6 month (or you have a contract with fixed IP).
At least for Germany a usual private DSL contract of any provider disconnect/reconnect you every 24 hours. And (without an expensive business contract) you ALWAYS get a different IP-address assigned. As I have friends with a typical private DSL connection I am sure that it is no problem to get a new IP during watching (picture freeze during reconnection of course - no internet = no decoding), its not even shown as error/rule-violation in the connections history but lists the IP-address you have had at this day. Also happens from time to time that DSL connection quits/router resets or something like this during watching: no problem in connection history shown.
But if you switch you emulator (Mgcamd to Oscam, or CCcam) directly the first time you get a notification about rule violation and using multiple receivers in the history (but don't bother at least in case of one or 2 switches nothing happens to anyone I know) ! you should really fix this
But by my knowledge the server recognize the country you connect from. So if you have a VPN connection (not allowed at all, never understand the reason why) to a different state and switch it to your home state or any other one, this is also a rule violation (and I don't know how strict this is handled).
