Is there a guide to get an two sperate tuners working together?

I am tired of Comcast and I am ready to just drop their PVR and stick with recording OTA for my HD via the HDHR and use my Haup 500 for the analog channels. Assuming those will still be available thru comcast.

But I am unsure how to get the EPG to play nicely with the two different tuners. I want to stick with the VMC interface so I can use my 360 as an extender and it also works nicely with MyMovies. Unless there is a equal alternative that has a WAF.
