My problem is in title: my dm500HD is not react to remote controll if NO HDMI cable is connected.

My DM500HD is connected with my Onkyo S506 HDMI receiver. If am turning
OFF my Onkyo (=kill HDMI connection between TV and DM500HD) I can't start (and even cant send to standby) my DM500HD anymore from remote control. Only from front panel of DM500HD. Sometimes I can turn it on by pressing power button repeatedly on the remote or I keep button press. After a couple of hours (after a night) this trick not working.

I am using latest kernel.

I attached a full log of the process, captured by HyperTerminal.

Maybe something with EPG cache daemon? How i Can disable it?
