I just setup WMC w/ a Ceton InfiniTV4 on TWC (with a tuning adapter). It works mostly well, but sometimes when I tune to a channel it doesn't load. It says black for a few seconds then says "you need a subscription". However, like 70% of the time if I channel up once or twice then channel back down, it loads within a second. If that doesn't work I can usually rinse and repeat and it'll eventually tune. Needless to say this can be irritating, and also worrisome if it fails to tune for a recording.
Can you guys help point me in a direction to troubleshoot? Could this be a WMC configuration issue, or perhaps something with my SDV tuning adapter? When I use the Ceton diagnostic tool, anytime I tell it to check a channel it works (I never get an error from the diagnostic tool).
