I downgraded to 7520 to try and keep my HDHomeRun working, except I now discover after updating the OS that somehow despite having check for updates unchecked in the preferences it has atomatically updated 7522.
This is appalling behaviour. Frankly, I'd have paid a low annual fee for access to the software if anybody had asked. Instead, I suppose I'll need to check where my dad bought me my HD HomeRun from and ask for a full refund. I can't see how it's acceptable within UK or EU consumer law to discontinue support so rapidly for a purportedly supported device I had specifically asked for as a gift. It's not a cheap product.
