HVR1600 Newbie - How to switch between tuners?

[bowulf]

I have changed from PVR150 to HVR1600, and got all the channels working using WinTV. I have setup both tuners within GBPVR and configured the channels using Zap2It. The first tuner is cable analog tuner, and that configuration continues to work fine. I just don't know how to change to the second tuner or use the second tuner's channels.

GB-PVR doesnt give you the option to manually select which tuner is used.

It follows a set of rules for which tuner it uses. When scheduling a recording it works it's way down the capture source list looking for an available capture that has the required channel. When starting live tv, the logic is reversed and it works its way up from the bottom of the capture source list.
