Ok this is hopefully an easy answer but I can't for the life of me find it in the docs or after hours of searching here and the mythtv user lists.
Is there a way to specify Channel Recording Priorities on a per tuner basis?
I have a pvr-150 and a pvr-250 being fed through a cable splitter. The 150 has vertical bars and distortion on a few channels (I think the splitter is causeing it) and I would like to be able to downgrade the priority of those channels but only on the pvr-150. I think it might be possible if I setup another duplicate video source in mythtv-setup but I'm not sure if that would cause other issues and also I believe then I would be pulling down the data from zap2it twice, which is less than ideal.

So what is the best way to reduce the priority of a channel on only 1 tuner? Thanks.
