Timer recordings seems to work, but they don't, as the recordings turn out empty. Zero minutes and seconds. Direct recordings work just fine.
Edit: I'm using a double tuner block, and it seems like only one of the inputs get signal through, and this is the upper input. I deleted the upper (C) input, and used only the lower (D) to test if I could watch a program, but the screen is black. It has full signal, but no picture. On the screen I get a message reading something like this: No data on transponder (Timeout reading PAT)
