If you read past that post your question was answered, it is a satellite PVR where as the t4-r needs an aerial. I hope you are not expecting the Aura EZ to actually record Freely, everything now suggests it will be just a Aura like Freeview recorder with Freely streaming capability and the existing Humax Aura has been riddled with flaws and faults since its launch years ago with many never addressed so hopes for this new Aura EZ are not too high which may make buying a t4-r and then adding an Aero a better option, you get 1 less tuner but more channels and Netflix with what may be a less glitchy product from a company that is better at updating and fixing problems than Humax are.
2TB T4R £229 + £69.99 for an aero Freely box or £249 for a Aura EZ. I think the extra £50 is worth considering for the extra benefits of Tivo and even more so if the EZ is anything like the existing Aura and I look forward to hear how you get on with your purchase in a couple of days, good luck.
