Can I assign a tuner to a favorite?

[gilded07]

I added a Phillips 12dB (50-900MHz) signal booster right before the split to my PVR150 and PVR500 (I believe the PVR500 counts as another split since it has two tuners). After the split last split, each coax goes directly into the 150 and 500.

I still have occasional problems with channel 5 / CBS and my favs are on Monday night back to back to back. The playback from some Monday nights is clear and comskip works fine. On other Monday nights, the playback picture is clearly worse than usual and comskip doesn't mark the coms at all or does so wrongly. I think my comskip version is 79.76.

I wonder if it has to do with one of my tuners being worse than the other (150 and 500). To test this theory, is there a way to assign tuners to a favorite? If I could reproduce the problem consistently with one tuner or the other then I could assign the better tuner to record my CBS favs and use the other for live TV (which doesn't suffer from picture quality at any time or with any channel).

Thanx.
