They appear the same whether I play them in MythTV, or download to VLC or in the HDHomerun Windows app.

I don’t know if you have similar where you are.  One other thing to check is the hdhrconfig command line utility. It lets you capture the signal, and shows you the status of the received data. This will make sure that you don’t have problems with network traffic problems.  As far as antenna recomendations, your fellow TV enthusiasts in your area may be able to assist more.

Oh.. another thing that may affect signal.. is trees between you and the broadcast source.

I'm wondering if this could be my problem, and if so why would the signal strength be so continuously variable?

Yep, that’s the problem.  Sounds like are receiving a dirty signal .   In the US / Canada, we have a website rabbitears.info <http://rabbitears.info/> that helps with giving an idea of what kind of signal  we can get for a given station. 

Sounds like you need a better antenna if possible..
