Will have to be careful here... It will be important that whatever lineups you have selected in your other SD app, are also selected in PiGS, even if you dont pick channels from that other lineup, otherwise PiGS will add/delete to make its lineup match SDs. this is b/c SD allows for 4 lineups max.I already have the SD subscription,
eg, you currently have lineup A and B with your other app. if you only add lineup A to PiGS and click Save Settings, PiGS will delete lineup B in your SD account.
when you get to that point, let me know - i suspect there are not a lot of dual client SD users out there.
