I have Windows 7 Media Center with 2 tuners.

I set shows to record with some room for error - 2 minutes before, 2 minutes after.
If I have two shows scheduled to record, one after the other, on the same channel, there's a 4 minute overlap between shows. Even if the other tuner is free, media center wants to continue using the same tuner! You end up having to watch the start of the next recording for the end of the current recording.

Does anyone know how to get it using the other tuner.
If not, does Windows 8 continue this behaviour?

Cheers
