Does your EPG show more than one episode in the same weekly time slot? Are you using MC2XML with the new shows (*) and you already recorded the next episode recently? I cant remember what PVRX2 uses for a memory of previous recorded shows, maybe 60 days (?) and if you recorded it before, it is remembering that and it wont record duplicates. In config, I think there is a checkbox "Don't record duplicates" maybe check that too and check/uncheck accordingly.
