I found tech support reasonable. They sent me a firmware upgrade nearly a year ago via email (it's not on their site for some reason). The upgrade was an improvement and easy to install using a usb stick.
My unit has the same freezing problem mentioned elsewhere. You get what you pay for and for the money it's OK although annoying when it does freeze during a recorded show. We switch ours off and on at the wall to reset it once every couple of weeks to reduce the chance of problems.
