I have a system with a pair of PVR-150s running MythDora 10.21 and both tuners 
work fine.

Not sure what that means, but it's another data point.

Many different tuners were used in cards called 'PVR-150', and there were many 
different models, some with remote interfaces, some without, some with radio 
tuners, some without etc. But even cards with identical features might have 
different tuners, I wonder if this has something to do with these reported 
problems, you can't expect the IVTV devs to have one or more of each version 
of the card.
