You cant have PVR, because your firmware do not have code for it. In other words - no application on TV witch could make records. (you could set it on on ServiceMenu, but it does not work).

You can`t put any other firmware except original one you have on TV already. It is impossible to have PVR on your TV. (just models from C650 and C630 with T-VALDEUC)
