Windows 7: When recording a program the pause/rewind buffer isn't saved

I've relatively recently been forced to switch to Media Center to maintain control over my own recordings. The digital cable switch last year has meant only CableCard devices will work and my cable company copy protects everything minus broadcast, so Windows is it for the most part.

So 7MC is very new to me, but I've had it running for a couple months now, everything working great. Quality is great, and the windows hardware support is great too.



I've long used DVRs from TiVo, MythTV to the Motorola DVR my cable company provides. All of them will add the pause buffer for a show into the recording once you hit the record button, for some ad-hoc recording. Say its 12 minutes after a program like the news starts. My pause/rewind buffer will allow me to go all the way back to the beginning of the news. All other DVRs I've ever used will add those 12 minutes into the final recording. 7MC seems to record only from that point on. So if you pause a show thinking you'll only be a few minutes, then come back 10 minutes later and decide to record and watch later, you won't get those 10 minutes in the recording.

Is there ANY way of fixing this, it is driving me insane the amount of things we've missed because of this bug / feature?

I'm using an old Athlon system with the later Windows 7 Pro. I have an HDHomerun Prime 3 Tuner device.
