ITVBe says it is showing The Only Way Is Essex, ITVBe +1 says Million Dollar Listing New York. They both appear to be correct. What platform are you watching on?
You haven't done something strange like pause your playback, wandered off, came back and hit the play button again?
This would generate a "Be+2" effect, if you're time shifting a time-shift...
It's possible that the schedule is running slightly later than it should be for whatever reason, either that or something's wrong with the data on your box and you should try turning it off and on again.
Well nobody else seems to suffer the problem so best thing to do would to either stop watching Be or make contact with Virgin. If the problem is only with you that suggests you have an issue with your setup. If ITVBe+1 was genuinely behaving like a +2 channel other people would experience it, and they haven't AFAICS.
Is it the programme or the EPG listing that is wrong? If it's the listing could it just be that your guide has gone wrong somewhere and maybe a restart of your box could fix it?
